The impressive ICM2002 opening ceremonywas held at the Great Hall of the People in Beijing in front of more than6000 Chinese and foreign mathematicians. This event undoubtedly signalsthe beginning of the final phase in China’s steady march towards being aworld’s mathematical superpower.We had unfortunately failed in our efforts to get senior Canadian offi-cials to present the Fields medals at the ICM2002 opening ceremony inBeijing.  Many thanks to the dozens of colleagues who wrote in support ofthis initiative.Chinese President Jiang Zemin Confers the (Canadian) Fields Medals in Beijingsee letter to Prime Minister on page 20Fields Medal winner Vladimir Voevodsky, Chinese President JiangZemin, IMU chairman Jacob Palis and Fields Medal winnerRoland Lafforgue at the ceremony in Beijing.NSERC Reallocation Results, PIMS: A modelfor the research institute of the 21st centurythe international leadership shown by the Ca-nadian mathematical community adding:“Here, PIMS seems to be in the driver’s seatwith incredible results for the world’s math-ematical community”.  Another referee con-curred: “Although [PIMS] is the youngest ofthe three, I believe that its reputation is rap-idly on the rise, so I find the incremental fund-ing which is requested in the PIMS proposal tobe compelling. I believe that the leadership ofPIMS is energetic and creative, and PIMS isperhaps the most ambitious of the three Cana-dian Institutes”. continued on page 2NSERC’s reallocations results are out andPIMS and the Canadian mathematical commu-nity have every reason to be proud of the ac-complishments of the last 5 years.The site visit report had much to say aboutthe institute’s contributions: “PIMS activitieshave broken through discipline and geographi-cal boundaries”. They echoed the refereescomments: “PIMS has become in a very shorttime a model for the research institute of thetwenty first century” and “PIMS has movedfrom an “idea” to a leading international in-stitute”. One anonymous referee wrote aboutNSERC Funding for PIMS up 60%“PIMS is emerging as the most exciting/dynamic research institute of the three math institutes inCanada. The vision driving this institute has, in 5 years, resulted in national (MITACS) andinternational (BIRS, Pacific Northwest Partnership, The Pacific Rim Initiative) initiatives whichhave done the most to raise the profile of Canadian mathematical research nationally and inter-nationally. The specific proposals, individually and collectively, build upon a bold vision for theinstitute. The innovative programs (Math and Multimedia, summer schools in emerging areas,webcasting) and the outreach programs (BIRS, Pacific Rim, Prairie and Atlantic Canada) standout particularly. The leveraged funding is extremely good for a mathematics institute. I whole-heartedly endorse the full reallocation request for this dynamic center.”That was one of the many compelling testimonials by a number of international refer-ees.  The reallocations committee awarded PIMS a 60% increase in its NSERC grant.Vol. 6, Issue 22Pacific Institute for the Mathematical SciencesNSERC Re-allocation Results:PIMS: A model for the research institute of the 21st centuryPIMS activities have brokenthrough discipline and geo-graphical boundariesSite visit committeeNSERC equalizes its funding for CRM,FIELDS and PIMSThe site visit committee also stated that “PIMShas been successful at multiplying the oppor-tunities provided by NSERC funds. However, itis also particularly underfunded compared tothe other two institutes.” NSERC’s realloca-tions committee  agreed by awarding PIMS a60% increase in its budget. Each one of the 3Institutes  (PIMS, Fields and CRM) will re-ceive a grant of approximately  $1 million/yearfor the period 2003–07. In addition, a joint pro-posal of the 3 institutes with the Statistics GrantSelection Committee (GSC 14) for a 4-year“National Programme on Complex Data Struc-tures” has also been funded at the rate of $172K/year.NSERC increases its funding for the Math.Grant Selection CommitteesThe synergies between the math communityand the institutes have again played a majorrole, even as the institutes carry on with theiroutreach efforts to other disciplines.  Indeed,Mathematics is one of only six submissions(out of 19 GSCs) that ended up with a budgetincrease: A major change from the dynamic ofthe first NSERC re-allocation exercise in 1994.The reallocations committee first recognizedthe importance of increased funding to newapplicants by returning $805K/year to the GSC336/337. In addition, the committee allocated$270K/year to promote structured initiativesby recognized leaders. Indeed, this innovativeapproach was well received by the CommitteeNassif Ghoussoub, PIMS Directorcontinued from page 1which noted that “initiatives that are builtaround a leader have been a recognized modelfor success in mathematics and other disci-plines. The institutes are also using this modelquite extensively”.All are encouraged to take a look at theNSERC webpage so as to be aware of the newopportunities created by this result. Congratu-lations to all involved, espe-cially to Richard Kane andRobert V. Moody who ledthis year’s exercise for math-ematics with exemplary judg-ment, skill, and patience.Referees’ unanimity on the Banff Interna-tional Research StationBIRS has been referred to—in almost all refer-ees’ reports—a major coup for the Canadiancommunity. The annual budget of BIRS is about$2M ($500K from each of NSF, ASRA, andNSERC’s MFA program; $100K fromMITACS and $400K from PIMS). In addition$1.1M have finally been secured to renovateand upgrade the facilities ($300K from thePIMS universities and $800K from the Albertagovernment).  We have an outstandingprogramme scheduled for 2003 and we have acall for proposals for the 2004 programme.Many thanks to Robert V. Moody for the in-credible amount of work and energy he is in-vesting to help set up this great continental re-source.The MITACS network up for renewalThe MITACS Network of Centres of Excel-lence developed by the 3 institutes has been agreat boost to the  applied and indus-trial mathematical science communityin Canada. It has continued to thriveunder the capable hands and entre-preneurial spirit of Arvind Gupta.  The$14.4M grant (given for the period1999/03) is up for renewal next year.We invite the math. science researchcommunity to join the institutes invigourously preparing for a success-ful renewal of MITACS.Supporting Atlantic Canada and thecompletion of the National Network forCollaboration in the Mathematical Sciences(NNCMS)The directors of CRM, Fields and PIMS havejust finished a tour of universities in AtlanticCanada, for the purpose of trying to completethe National Network for Re-search in the Mathematical Sci-ences (A first attempt at anNSERC’s RPP research net-work had failed in 1997!).  The3 institutes funding  for AARMS(Atlantic Association for Re-search in the Mathematical Sciences) has beenmatched by the Memorial University of New-foundland in St. John’s, the University of NovaScotia at Dalhousie and the University of NewBrunswick at  Fredericton. In addition,MITACS has committed substantial funds forseed projects subject to appropriate matchingfrom the provincial governments and local in-dustries. The $600K/year package should pro-vide a great boost to Atlantic Canada researchin the mathematical sciences.  Here HermannBrunner is to be heartily congratulated for hisefforts and leadership.The National Programme Committee to berestructuredThe National Programme Committee of the 3institutes will be restructured soon so that itcan effectively deal with the developing pic-ture across the country. Every active Canadianresearcher should/will have access to theinfrastructural resources and to the researchopportunities, new and old.Celebrating PIMS success at NSERC’s re-allocation exercise.PIMS: Un institut sansfrontières disciplinairesni geographiques.N. GhoussoubFall 2002 3Pacific Institute for the Mathematical Sciencesand Nassif intrigued me.  Nassif and the othermathematical scientists on the Board had littleto no administrative experience.  I had lots ofadministrative experience so they thought I wasbrilliant, which goes to show you can fool someof the people some of the time!  Many of theprivate sector members of the Board were lead-ers in their own right, and they had a vision ofhelping to build something great.  It was a plea-sure to work with them as well.In your opinion, what sort of impact hasPIMS had on U of A?Tremendous!  PIMS has given our mathemati-cal and statistical scientists the opportunity towork more with others in research, to workmore with industry, and to do more in matheducation - all of which would have otherwisenot been available.  It has given the Depart-ment the opportunity to be a leader.While you served as Dean you have re-mained active with your research.  Give usan outline of your main interests.My research is on the brain regulation of foodintake, growth and reproduction in fish.  Wework on the brain hormones that regulate thesefunctions.  In the last few years I have switchedmost of the research in my lab to food in-take regulation, a new area in research forfish.  We work from the molecular biologyto behavior levels—a challenge!  It’s funto be in a new field.  The best is that I havehad the privilege of having outstandingPDFs, graduate students and undergradu-ates to work with in my lab.How do you think BIRS will benefit theprovince of Alberta?Tremendous!  The world spot light will beon PIMS as being the leader in BIRS.Through BIRS the opportunity presents it-self for Alberta universities to become bet-ter known and to develop leadership in re-search.Now that you are retiring from your po-sition as Dean, what are your plans forthe near future?  Please tell us aboutsome of your other interests.I started as Vice President, Integrated ResourceAn interview with Dick Peter, exiting Dean of Science, UAby Heather Jenkins, PIMS Communications OfficerDr. Richard E. Peter recently finished a 10-year term as Dean of Science at the Universityof Alberta.  He is also a distinguished Profes-sor in the Department of Biological Sciences.He has been a member and deputy Chair of thePIMS Board of Directors since PIMS wasfounded in 1996.Dean Peter, you have been a part of PIMSsince the beginning.  Can you tell us some-thing about the early days?The vision of PIMS - to have mathematicaland statistical scientists working together onresearch themes, working together on industryproblems, and working together on math edu-cation - was something needed.  I saw the com-munity as being quite fractured and ineffec-tive, and missing the boat on many opportuni-ties.  PIMS looked like a great opporunity toget things going.  It turned out to be true!As Dean of Science at U of A you have madethe Mathematical Sciences a priority.  Whydid you chose to do this?The mathematical sciences are the foundationfor all areas of the sciences.  We needed strongmathematical sciences research and teaching tobe a strong Faculty of Science.  Building astrong Mathematical and Statistical SciencesDepartment was one of my many priorities.  Iam pleased with the success of our recruitmentof new faculty.  Now the challenge for theDepartment is to have a view of itself as beinga leader, and taking actions to do so.You have been a very active member of thePIMS Board of Directors.  How would youcharacterise your contribution to PIMS?Being a member of the Board was a priviledgeand an honor.PIMS was new.  I was caught up in thevision for PIMS.  Nassif Ghoussoub kept ex-panding the vision, which made the Board in-teresting and challenging.  Just when youthought one thing was sorted out and underway, Nassif would come up with another greatinitiative.  The vision was great!  Being a mem-ber of the Board gave me the opportunity towork towards the vision of PIMS and to helpthe vision become a reality.I must also add that the people on the BoardManagement at the Alberta Research Councilon August 1, 2002.  This is an opportunity tolead the development of a program and researchteam that provides government, industry andcommunities practical information and adviceabout natural resource management, and newtechnologies and approaches for sustainabledevelopment.  This is applied interdisciplinaryscience.  Funding has to be brought in fromgovernment and industry or the research teamwill not exist.  So, while the goals are noble,and society, governments and industry willbenefit if we are successful, there are lots ofchallenges to make this a success.Other interests?  While my job at ARC isfull time, I still have my research lab at theUniversity of Alberta going full pace with anoutstanding PhD student and two PDFs.Three other PDFs went off to jobs during thesummer.  On the personal side, my wife and Iare taking a sommelier course and enjoying itvery much.  The challenge now is to build (i.e.,fill) a wine cellar in our new home, which wemoved into in July.  Our new home comes withno shovelling or mowing - just shut the doorand travel when the opportunity presents.Thank you Dean Peter.Dick Peter, University of AlbertaVol. 6, Issue 24Pacific Institute for the Mathematical SciencesThe Banff International Research Stationby Robert Moody, BIRS Scientific DirectorAlthough it is still 6 months to the openingof BIRS, lots of things are happening on thelong, sometimes arduous, ramp-up process.The most significant developments since ourlast Newsletter are that all the funding is nowin place, including the critical funding from theAlberta Science and Research Authority(ASRA) for the necessary renovations at theBanff Centre and that these renovations arenow underway. BIRS will be physically lo-cated in two adjacent buildings at the BanffCentre: the Max Bell building will have twolecture rooms and several smaller meeting anddiscussion rooms, and Corbett Hall, which willbe entirely taken over by BIRS, will house theliving quarters for all BIRS visitors. Both in-volve extensive renovations (total cost exceed-ing $1M). After well over a year and half ofdealing with BIRS as a virtual entity, it is fi-nally beginning to take a physical form.It is a bit startling to realize that even beforeBIRS opens its doors for business in March2003, the entire workshop programme for both2003 and 2004 will be in place. But given thetime for adjudication and the need to give or-ganizers and participants a clear year of ad-vance notice, the 2004 competition has to be inthe fall of 2002. That means now.The Call for Proposals for 2004 is alreadyout!Please check out the PIMS website. Thereis a considerable amount of information on thevarious BIRS programmes and the review pro-cess, as well as guidelines and online forms.The whole idea of BIRS is to take the adminis-trative burden off organizers to let them  con-centrate on the science. If you have any incli-nation to organize something at BIRS, take alook and see how easy it is. The deadline forworkshop submissions is October 15, 2002.We also strongly suggest that you think ofOctober 15 as the deadline for the other BIRSprogrammes too (research in teams, focusedresearch groups, summer schools, etc.). TheScientific Steering Committee of BIRS willmake its first round of decisions on theseprogrammes soon after this date, and competi-tion for space for the prime summer monthswill most surely be taken in this first round.This brings us to another substantial devel-opment. In February Jessica Douglas joinedthe PIMS (UBC) staff as the Scientific Coor-dinator of BIRS. Jessica is the contact personfor all BIRS scientific programmes.  Jessicahas also been working hard to make the BIRSwebsite as useful as possible for organizers,participants, applicants of proposals, referees,and members of the scientific selection com-mittees. You will notice substantial differences(and I hope improvements) to the appearanceof the BIRS website. Underneath this there aremany more developments, which allow every-one to interact with BIRS painlessly online.Jessica and Heather Jenkins (PIMS Commu-nications Officer) also created the beautifulposter for the 2003 Workshop programme ofBIRS.  The credit for set-ting up the webpage and formany of the details of pro-gramming the data-basegoes to the very able KellyChoo (PIMS Website Man-ager) at the University ofVictoria.  Sandy Ruther-ford (PIMS Scientific Ex-ecutive Officer) andShervin Teymouri (PIMSComputer Systems Man-ager) are setting up the com-puter system at BIRS.Focused Research Groups (FRG),Research in Teams (RIT) andSummer Schools (SS)2003 ProgrammeApr 26–May 10  Topological Orbit Equiva-lence for Dynamical Systems (RIT)T.

The scientific committee was co-chaired by Vitali Milman (Tel Aviv) and NicoleTomczak-Jaegermann  (Universi ty ofAlberta).  The other members of the committeewere Nassif Ghousoub (PIMS and UBC),Robert McCann (University of Toronto) andGideon Schechtman (Weizmann Institute).Asymptotic geometric analysis is concernedwith the geometric and linear properties of fi-nite-dimensional convex bodies, especiallywith the asymptotics of various quantitativeparameters as the dimension of the underlyingspace tends to infinity.  This field is multi-dis-ciplinary in nature, typically combining geo-metric, analytic, probabilistic and combinato-rial methods.This Thematic Programme brought togetherover 220 senior experts, young researchers,postdocs and advanced Ph.D. students frommathematics and computer science.  Repre-sented among the programme of speakers werelaureates of many different honours and prizes,such as the Fields Medal,Nevanlinna Prize,  WolfPrize,  Salem Prize,Ostrowski Prize, and manyothers.  The flavor of theworkshop may be felt fromthe following examples ofspeakers and directions (inbroad categories and listedin every group alphabeti-cally). Many more talks inevery direction were, in fact,given.• In the field of AsymptoticCombinatorics (which in-cluded also lectures relatingto graph and informationtheory), lectures were given by Noga Alon (TelAviv University), Imre Barany (UniversityCollege London), Jennifer Chayes (Microsoft),Gil Kalai (Hebrew University), MichaelKrivelevich (Tel Aviv University), LaszloLovasz (Microsoft) and Miklos Simonovits(Hungarian Academy of Sciences).• Keith Ball (University College London),Apostolos Giannopoulos (University of Crete),Yehoram Gordon (Technion), Hermann Koenig(Universität Kiel), Vitali Milman (Tel AvivUniversity), Gideon Schechtman (WeizmannInstitute), and Nicole Tomczak-Jaegermann(University of Alberta) lectured on Asymp-totic Geometric Analysis.• Classical Convexity was represented, forexample, by lectures given by Erwin Lutwak(Polytechnic University), Rolf Schneider (Uni-versity of Freiburg), and Peter Gruber (Uni-versity of Technology, Vienna).• In the direction of Analysis, Jean Bourgain(IAS), Alexander Koldobsky (University ofMissouri-Columbia), Izabella Laba (UBC),Mikhail Sodin (Tel Aviv University) spoke.• Complexity Theory was represented by thetalks of Ravi Kannan (Yale), Shmuel Safra (TelAviv University), and AviWigderson (Institute forAdvanced Study).• Talks on Statistical Phys-ics and Random Matriceswere given by ChristianBorgs (Microsoft) ,Ravindran Kannan (YaleUniversity), Leonid Pastur(Université Paris VII),Alexander Soshnikov (Uni-versity of California,Davis),  and StanislawSzarek (Université Paris VIand Case Western Re-serve).• Franck Barthe (Université de Marne-la-Vallée,CNRS), Yann Brenier (CNRS), Jose A. Carrillo(Universidad de Granada),  and RobertMcCann (University of Toronto) gave lectureson the Transportation of Measure.• Lectures in Probability Theory were givenby Rafal Latala (Warsaw University), MichelLedoux (Universi té de Toulouse),  andKrzysztof Oleszkiewicz (Warsaw University).• Edward Effros (UCLA), Marius Junge (Uni-versity of Illinois), Alexandru Nica (Univer-sity of Waterloo), Zhong-Jin Ruan (Universityof Illinois), and Roland Speicher (Queen’sUniversity) represented Non-commutativePhenomena.• Lectures on Infinite Dimensional BanachSpaces were given by Tadeusz Figiel (PolishAcademy of Sciences), Joram Lindenstrauss(Hebrew University), Aleksander Pelczynski(Polish Academy of Sciences), HaskellRosenthal (University of Texas), and ThomasSchlumprecht (Texas A&M University).This list is only an excerpt from the veryrich programme of talks.  For the complete listof participants and lectures see the AsymptoticGeometric Analysis Thematic Programmewebpage www.pims.math.ca/aga.Close to 100 of the lectures in theprogramme were taped and are available in bothstreaming realvideo and MP3 formats.  Thisprovided an online resource to conference par-ticipants, allowing them to review previous lec-tures throughout the programme.  To provide aresource to the mathematics community at large,we have now made entire collection of tapedlectures available from the main ThematicProgramme webpage given above and from thePIMS online lecture archive,  http://www.pims.math.ca/video.The main directions of study were convexgeometric analysis (asymptotic theory of con-vex bodies and normed spaces), some prob-lems of discrete mathematics (one may call itasymptotic combinatorics) including problemsof complexity theory, and some problems ofstatistical physics.  A number of lectures werealso given on closely-connected subjects inprobability and nonlinear PDEs arising in con-vex analysis and geometric inequalities.Fields medalist Jean Bourgain, IAS.Fall 2002 7Pacific Institute for the Mathematical SciencesThe Programme was divided into six sec-tions: a Conference on Convexity and Asymp-totic Theory of Normed Spaces, a Concentra-tion Period on Measure Transportation andGeometric Inequalities, a Conference on Phe-nomena of Large Dimensions, a Focused Re-search Groups Session on Random Methodsand High Dimensional Systems, a Conferenceon Non-commutative Phenomena and RandomMatrices, and a Conference on Banach Spaces.The programme was strongly connected the-matically with many of the lectures illustratingthe cross-over between these fields.  Most ofthe participants took advantage of this by at-tending a number of the sessions in theprogramme.Conference on Convexity and AsymptoticTheory of Normed SpacesThe programme opened with the Conferenceon Convexity and Asymptotic Theory ofNormed Spaces, organized by Erwin Lutwak(Polytechnic University) and Alain Pajor(Marne-La-Vallée).  Lasting one week (July1–5) this conference featured lectures on clas-sical convexity theory, Radon transforms andFourier methods in convexity, asymptotictheory of high dimensional convex bodies, geo-metric functional inequalities, probabilisticmethods in convexity, and isoperimetric-typeinequalitiesConcentration Period on Measure Trans-portation and Geometric InequalitiesThe second week of the Thematic Programmewas devoted to the Concentration Period onMeasure Transportation and Geometric In-equalities, which was organized by RobertMcCann (University of Toronto).  The focuswas on transportation of measure methods andtheir applications, including concentration ofmeasure phenomena, geometric functional in-e q u a l i t i e s(Brascamp-Lieb,Sobolev, entropy,Cramer-Crao andthe l ike),  andp r o b a b i l i s t i cmethods.  Thisconcentration pe-riod was orga-nized with aslightly lighterlecture scheduleto allow ample time for extensive informal dis-cussions between lectures.Conference on Phenomena of Large Di-mensionsThe Conference on Phenomena of Large Di-mensions ran from July 15–23.  It was orga-nized by Vitali Milman (Tel Aviv), MichaelKrivelevich (Tel  Aviv),  Laszlo Lovasz(Microsoft Research) and Leonid Pastur (U.Paris VII).  The main topics covered in thelectures were different phenomena observedin complexity theory, asymptotic combinato-rics, asymptotic convexity, statistical physicsand other theories of very high parametric fami-lies (or large dimensional spaces).Focused Research Groups on RandomMethodsThe period from July 24 to August 5 was de-voted to the Focused Research Groups on Ran-dom Methods and High Dimensional Systems.Participants took advantage of this period todiscuss previous lectures in the programme andto work in newdirections.

Paris VI andTexas A & M) and Stanislaw Szarek (U. ParisVI and Case Western Reserve).  Topics ad-dressed in this conference related to the distri-bution of eigenvalues of random matrices,norms of such matrices, some aspects of freeand quantum information theories, quantizedfunctional analysis and operator spaces, andnon-commutative Lp spaces.Conference on Banach SpacesThe programme closed with the Conference onBanach Spaces, which was organized by BillJohnson (Texas A & M) and Ted Odell(U. Texas, Austin).  Unfortunately, personal cir-cumstances required Bill Johnson to cancel hisparticipation at the last minute and his pres-ence was greatly missed.  This conference fo-cused on the asymptotic theory of Banachspaces and other applications of local theory tothe geometry of infinite dimensional Banachspaces.PIMS is grateful for the additional supportprovided to this Programme by the CRC grantof Nicole Tomczak-Jaegermann, by the NSFconference grants of Erwin Lutwak and TedOdell, and by Microsoft.  Furthermore, wethank all of the organizers, speakers and par-ticipants for making this Programme such asuccess with their enthusiasm and dedication.Vol. 6, Issue 28Pacific Institute for the Mathematical SciencesKneeling (L-R): Y.

Our aim was to introduce under-graduate mathematics students to mathematical modeling and analysis applied to real biological systems.  Instruc-tors were Gerda de Vries, Thomas Hillen, Mark Lewis, and Michael Li, all from the University of Alberta.  Therewas further assistance provided by volunteer graduate students, postdoc fellows, and staff (Robert Bechtel, Andrew Beltaos, Gustavo Carrero,Christina Cobbold, Tomas de Camino-Beck, Lisa Haraba, Annemarie Pielaat, Shirley Mitchell).We received applications from almost 40 students from all over North America.  In the end, 26 students came to the workshop from 14 differentUniversities across Canada and the United States, many on their own funding.  More than half of the attendees were women.The workshop was 8 days in length and was a combination of classroom instruction, computer lab instruction and exercises, guided groupproject work, and project presentations.The extremely positive feedback that was received, in combination with the large number of applicants and participants, has led us to pursuethe workshop as an annual event.  We strongly believe the exchange of ideas and knowledge that occurred between students will be carried backto their home universities and that the program will grow in popularity over the years to come.Photographs and presentations from the workshop can be found at: www.math.ualberta.ca/~mathbio/events.html.Nearly 100 researchers from 10 different coun-tries came to UBC last May to participate inthe International Conference on Robust Statis-tics (ICORS 2002) hosted by PIMS and jointlysponsored by PIMS, MINERVA ResearchFoundation (USA) and SBF 475 at Universityof Dortmund (Germany).  Participants gath-ered at PIMS to present and discuss recent re-search on robustness and computational statis-tics.

It is a great expe-rience to be a PIMS postdoc. You and all thepeople at PIMS are very kind and helpful,providing a very nice working environmentfor academic research.  During the past twoyears, I have enjoyed my life in Vancouverand I worked happily and enthusiasticallywith my professors.  More importantly, as anew immigrant, my whole life and academicexperience in Canda started from PIMS.Wherever I stay in the future, I will missPIMS and Vancouver for the rest of my life.I hope PIMS will be stronger and stron-ger in the future.Best regards,Yuqing WangFall 2002 11Pacific Institute for the Mathematical SciencesPIMS-APCTP-PI Frontiers in Mathematical Physics:Workshop on “Brane Worlds and Supersymmetry”University of  British Columbia, July 22– August 2, 2002Some of the extra dimension sce-narios use superstring theory to quan-tize gravity and predict  thatsuperstring excitations should be observableat much lower energies than was previouslythought.  The elementary particles seen so farwould be the lowest energy excitations ofsuperstrings.  The next excited states wouldoccur at energies not much higher than themasses of already observed particles.  This hasthe exciting consequence that these new ideasare testable by present and imminent experi-ments.  For example, the existence of extra di-mensions modifies the gravitational interactionat short distances.  If objects are close together,gravity would no longer have the Newtonianinverse square dependence on distance butwould have a different power depending onthe total number of dimensions of spacetime.There are now several new experiments dedi-cated to testing the laws of gravity at the mi-cron level.Lectures were given by:Alessandro D’Adda (INFN, Torino), Gaugetheories of the symmetric group in the large NlimitIgnatios Antoniadis (CERN), Physics withlarge extra dimension (2 lectures)Cliff Burgess (McGill), Fixing runawaymoduliKiwoon Choi (KAIST), Radius-dependentgauge coupling renormalization in AdS5Keith Dienes (Arizona), Shape versus volume:rethinking the properties of large extra dimen-sions and Solving the hierarchy problem with-out SUSY or extra dimensions: an alternativeapproachBogdan Dobrescu (Yale), Universal extradimensionAndreas Karch (Washington), Adding flavourto ADS/CFTEmanuel Katz (Washington), Little HiggsesNoboru Kawamoto (Hokkaido), Twistedsuperspace and Dirac-Kaehler fermionsHyung Do Kim (KIAS), Deconstructingwarped gauge theory and unificationC.S. Lam (McGill), What can neutrino oscil-Contributed by Sandy Rutherford, PIMSHeld at the Department of Physics and As-tronomy, UBC, this two-week workshop fea-tured a variety of talks on topics ranging fromfundamental questions in superstring theoryand supersymmetry to the cosmological impli-cations of brane world models and higher di-mensional physics.  Brane world models sug-gest that the observable universe is a domainwall (the word brane derives from membrane)in a higher dimensional universe.  These mod-els have been proposed as a possible solutionto the hierarchy problem, which asks why inthe standard model of particle physics the hier-archy of mass scales that is observed in naturecan occur.The standard model of particle physics is acomplicated nonlinear dynamical system.  Insuch systems, predictions of dimensional num-bers like particle masses tend to be of the samesize, the size of the largest input parameter.  Innature, there is a distribution of differentmasses, from massless particles like the pho-ton and the very light particles like the electronor neutrino to the mass scale which describesgravitational interactions, a factor of 1020heavier.  Previous to these new ideas, the onlysolution of this hierarchy problem was to in-voke symmetries.  In fact, supersymmetry — ahypothetical and as yet unobserved symmetrywhose transformations mix fermionic andbosonic particles — was needed. These newideas about extra dimensions give a radical newalternative solution of the hierarchy problem.This solution is so compelling that it has beenthe focus of intense theoretical particle physicsresearch over the past few years.The new ideas about extra dimensions havealso led to a revolution in our thinking aboutthe role of gravity in particle physics.  Gravitywas previously thought to be important to theinteractions of elementary particles only at ex-tremely short distance scales, 10-34 centime-ters, or in processes involving extremely highenergies, far beyond the reach of any conceiv-able experiments.  In most of the extra dimen-sion scenarios, gravity becomes an importantplayer in particle physics modeling.lation tells us about the possible existence ofan extra dimension?Y.S.

These problems arise in many areasof applications including geophysics, medical imag-ining, remote sensing and non-destructive evalua-tion of materials.During the last twenty years or so there hasbeen remarkable developments in the mathematicaltheory of inverse problems. These developmentstogether with the enormous increase in computingpower and new powerful numerical methods hasmade possible to make significant progress on in-creasingly more realistic and difficult inverse prob-lems. The purpose of the period of concentration isto bring together mathematicians and practitionersto work on these problems on these problem.

Washington)The workshop will focus on recent develop-ments in scattering and inverse scatteringtheory. In both these fields techniques ofmicrolocal analysis, including the use of eikonalequations and of complex geometrical opticssolutions to Schroedinger and other equations,has led to substantial progress in recent years.Scattering theory seeks an understandingof spectral phenomena for noncompact mani-folds. There has been a recent focus in thissubject on what is now termed geometric scat-tering, which amounts to the study of scatter-ing on classes of noncompact complete mani-folds with regular structures at infinity. Someof the questions asked here concern the smoothparametrization of the continuous spectrum byfunctions on some ideal boundary, the struc-ture of the scattering matrix as an operator onthis ideal boundary, and the study of resonances,which are poles of the meromorphic continua-tion of the resolvent. There are many subtleconnections between these objects and the ge-ometry of the underlying manifold.PIMS-MITACS Workshop on InverseProblems in GeophysicsPIMS, U.

The heterogeneity and anisot-ropy of the Earth’s upper crust require advancedmathematics to generate wave-equation solutionssuitable for seismic imaging.  The workshop willbring together mathematicians familiar with thesetechniques and geophysicists familiar with the prac-tical applications.PIMS-MITACS-IMA Workshop onIndustrial Applications of InverseProblemsPIMS-UBC, July 27–August 1, 2003Organisers: Fadil Santosa (Chair, U. Minne-sota), David Dobson (Texas A & M), GaryMargrave (U. Calgary) and Gunther Uhlmann(U. Washington).The goal of the workshop is to stimulate the cre-ation of interdisciplinary teams, consisting of math-ematicians, engineers and scientists, that would con-tinue working on inverse problems posed by in-dustry scientists at the workshop.  The teams willcomprise of a mix of senior and junior mathemati-cians that are broadly trained in mathematics and areinterested in collaborating with industry on real-world inverse problems.This workshop will concentrate on industrialapplications of inverse problems. The goal is todetermine defects, corrosion, cracks, very small in-homogeneities, cavities or inclusions by noninvasivemeasurements. The object under study is probedusing X-rays or electromagnetic and elastic wavesand the mathematical methods are based on the studyof inverse boundary and scattering problems.Workshop on Inverse Problems andMedical ImagingU. Washington, Seattle, August 4–8, 2003Organisers: John Schotland (chair), RichardAlbanese (Armstrong Research Lab, BrooksAFB), Tom Budinger (Biomedical Engineering,Berkeley), David Isaacson (Courant), AmirGandjbakhche (National Institute of Health) andGunther Uhlmann (U. Washington).This workshop will concentrate on recent develop-ments in medical imaging including the advances inengineering and image processing mathematicswhich have allowed for significant enhancement ofwidely used imaging techniques like X-ray tomog-raphy, magnetic resonance imaging, single photonemission tomography, positron emission tomogra-phy, ultrasound etc. Of particular interest is recentprogress in “elasticity imaging” which uses ad-vances in the mathematical study of wave propaga-tion in heterogeneous media for the evaluation ofmechanical properties of tissue inaccessible to touchby a physician.Vol. 6, Issue 214Pacific Institute for the Mathematical SciencesPIMS Collaborative Research Groupsby Nassif Ghoussoub, PIMS DirectorAs part of its second phase of development,PIMS is embarking on a plan that will createand support collaborative multi-universityteams of mathematical scientists.  These Col-laborative Research Groups (CRGs) will pooltalent across universities to form world-classresearch groups that will generate and sustainthe scientific programme of PIMS in the yearsto come.The research programs of these groups willbe supported through a new PIMS programthat supports concentrated activities in 5-10 re-search areas each year.  This programme, runon a competitive basis, will support multi-siteactivities of selected CRGs over a 1-2 yearperiod of concentration.What is a PIMS CRG?The CRGs typically consist  of researchers witha common research interest and with a com-mon desire to collaboratively develop someaspects of their research programs. Groups mayalready be organizing joint seminars and work-shops, making joint PDF appointments, or de-veloping joint graduate training programs.However, with the resources and organizationalstructure of PIMS they will be able to do con-siderably more.The CRGs act as a vehicle for networkingbetween universities. They effectively integratethe mathematical sciences community at thevarious PIMS universities into the scientificinfrastructure of PIMS. They will build on al-ready existing joint efforts and links betweenthe researchers of Western Canada and the USPacific Northwest thereby opening up a newera of scientific collaborations between the twocountries.  They will also will assume scien-tific leadership at the Banff Station and somewill have the potential to lead industrial projectsthrough the MITACS network.The CRGs will create critical mass that willsubstantially enhance training programs at alllevels. The pooling of PIMS support with othersources and the joint planning of resource allo-cation will allow the CRGs to support a largenumber of PDFs and graduate students andwill create new research opportunities for theseyoung scientists, including exchanges, jointsupervision, and summer schools.The CRGs directly address the problems ofretention and recruitment of faculty.  They area venue for new faculty to get plugged into alarger community, they give young faculty aneffective network to build their research pro-gram, and they enhance the attractiveness ofthe universities.PIMS has identified 32 potential CRGswithin its community, spanning five broad ar-eas of research to which PIMS is committed:Fundamental Mathematics, Applied and com-putational Mathematics, Mathematical Biologyand Medicine, Statistical Sciences and Theo-retical Computer Science. While some are al-ready well established and structured, in mostcases they are just forming. Each CRG, whichconsists of 10-15 Canadian and US research-ers, are to be jointly coordinated by at least 3senior researchers representing various PIMS’Sites.Periods of Concentrated activitiesfor the CRGsThe Periods of Concentration are designed topromote and support longer term, multi-event,multi-site coordinated activities of competitivelyselected CRGs, in tandem with their nationaland international collaborators and visitors.Every year, the PIMS Scientific Review Panelwill select on a competitive basis, up to 5 areasof research from those proposed by existing ordeveloping CRGs. The selected areas will bethe focus of much of the institute’s programover a 1–2 year period of concentrated activi-ties that will be delivered through the selectedCRGs.  Thus, at any given time, as many as 10CRGs may be leading the PIMS scientific en-terprise.  Proposals can vary greatly accordingto the needs of the particular group and maycombine a number of existing PIMS activities.During its period of concentration, a CRG canexpect to receive priority for:• Thematic programs and mini-programs• PIMS postdoctoral fellowships• Pacific Northwest mini-conference series• 5-day workshops at BIRS• Focussed workshops at host universities• Intensive two week graduate courses• Distinguished chairs & long term visitors• Graduate students exchanges• Graduate & senior undergrad schools• Industrial training camps• International collaborations• Teaching relief & sabbatical supplements.With this support, a CRG can plan to gathera significant portion of the world’s experts inits focus topic for periods of intense collabora-tion. The fruits of such intensity can be ex-pected to persist for many years and to be ex-ponentially greater than the results of morenormal activity levels.In due course, all 32 of the PIMS CRGsrecognized so far would be given the benefit ofa period of concentration. This approach shoulddramatically increase the effectiveness of thePIMS research program by making its facili-ties and its opportunities available to all CRGson a periodic basis.Expected Impact of the Periods ofConcentrationA targeted and coordinated, yet inclusive grass-roots approach of this form will present a newand innovative way for the institute to driveand stimulate research and will result in a sig-nificant impact on the research excellence ofits activities. The program’s extended timescale, its multi-event nature and its cross-uni-versity character together distinguish it fromany other institute program. Its implementa-tion will allow PIMS to achieve several of itsgoals. It will:• Provide new ways of having its scien-tific programs driven by its member scientists:The program will help elicit proposals for the-matic summers, miniprograms, BIRS events,and distinguished scholars as part of the appli-cation process. These programs will have stronglocal interest and will encourage grass-rootsgeneration and longterm planning of activitieswith a much more inclusive and flexible for-Fall 2002 15Pacific Institute for the Mathematical Sciencesmat than standard thematic programs.• Foster multi-site interactions and collabo-rations: The program will continue to build theinter-site collaborative nature of the PIMS com-munity and will alleviate the problems of inter-connection inherent in large geographical sepa-rations between the PIMS sites. It creates acontext through which researchers can collec-tively profit from the opportunities created byPIMS, the Banff station and the MITACS net-work.• Create new research opportunities andenhance training: The periods of concentrationwill allow for the planning of a series of ad-vanced graduate courses at any one site withthe participation of students from multiplePIMS universities. The Western Dean’s agree-ment allows graduate students at any WesternCanadian university to take courses, for credit,at any Canadian PIMS university. The resultwill be new opportunities for PIMS graduatestudents and a larger audience for PIMS andvisiting scientists. This will directly lead to avigorous graduate student exchange program.• Support existing collaborative researchgroups and foster new groups: The periods ofconcentration will help to strengthen groupsand give them a vehicle for long-range plan-ning of research and advanced education ac-tivities. As well it will encourage and empowerisolated groups or smaller ones at one univer-sity by bringing them into larger collaborativeteams.• Effectively facilitate Canada-US collabo-rations: The program will effectively integratethe mathematical sciences community at the U.of Washington into the operations of the insti-tute. It will allow the 12 groups of Canadianand US researchers that are currently organiz-ing the PNW Seminars to develop further theircollaborative activities, and allow other groupsto launch these types of activities. The pro-gram will also provide researchers with themeans to play a leadership role on the nationaland international level.• Attract additional support for research:Periods of concentration will provide depart-ments and universities with a mechanism forgranting teaching and administrative releasesto the scientists involved. Such programs canalso be developed in collaboration with otherorganizations and institutes, hence multiplyingthe opportunities.Upcoming Areas ofConcentration: 2003–06String Theory: 2003–05The concentration of researchers in string theoryand closely related fields in the PIMS and Perim-eter Institute communities has reached a criticalsize and has the potential to be a major player inthe international research community.Members of the CRG: B.

TorontoDavid Gillman, UCLAVol. 6, Issue 218Pacific Institute for the Mathematical SciencesIs Economic Theory True?By Dr. Ivar Ekeland, Université Paris-DauphineI. The problem of testingEconomic theory, like physics, works from the bottom up. For the physi-cist, objects, as we see them, are built from atoms aggregated in variousways. For the economist, society is a collection of decision-making indi-viduals who interact. So we need to know how people make decisions.Let us look at the simplest case of a lone individual, having an amountw ∈ R+ to spend on the purchase of K goods. If he buys the quantityxk of good k, he pays pkxk, where pk is the unit price of good k. Inclassical economic theory, his tastes are subsumed by a utility functionU : RK+ → R, which we will assume to be concave and smooth. The in-dividual then chooses the goods bundle x (p) which maximizes his utilityunder the budget constrain (throughout the paper, transposition is denotedby prime):maxxU (x) for p′x ≤ wSo the individual decision process is reduced to a concave optimiza-tion problem. It is a very simple model, and very tractable mathematically,but is it true? Certainly, there is little prima facie evidence for utility func-tions; we cannot just peer into ourselves and find it. So the problem oftesting the model is a difficult one, and we have to handle it in a round-about way. The basic idea is to look at the demand function p → x (p),which gives the choices of the consumer as prices change. Certainly, wayscan be devised to observe that. We get a map from RK into itself, andthe question is whether the theory predicts some properties which can betested against the observations.II. Testing with individual dataIntroduce the indirect utility function :V (p) = maxx{U (x) | p′x = w}By the classical theory of Lagrange multipliers, there is some λ (p) >0 such that:V (p) = maxx{U (x) + λ (p)(w − p′x)}where the maximum on the right-hand side is attained at x (p) . Applyingthe envelope theorem, we get:DpV (p) = −λ (p) x (p) (1)This is a remarkable relation, because it tells us that the vector fieldx (p) (which we know) is collinear to the gradient of an unknown functionV (p) . In addition, λ must be positive and V convex. This is a very strongcondition on x (p) , and the economists have long worked out some neces-sary and sufficient conditions (see for instance the treatise [4]). Introducethe so-called Slutsky matrix S (p) = (sij (p))i,j associated with x (p):sij (p) = ∂xj∂pi−∑kpk ∂xj∂pkxiThen x (p) can be decomposed in the form (1) if and only if its Slutskymatrix of x (p) is symmetric negative definite. In other words, the k partialderivatives of x (p) have to satisfy K (K − 1) /2 distinct conditions. Thisis a lot, and there are many conditions to be tested. They have been, andthe results make a nice story.Up to 1996, all econometric tests applied on collected data rejectedthe symmetry of the Slutsky matrix. That year, a paper by Browning andChiappori appeared, which did two things. First, they tested the symmetryhypothesis on data for singles. The point is that all collected data con-cerns household, not individual, consumption: when food is bought, it isfor the whole family. In previous tests, no provision was made to weed outdata concerning households with two or more individuals. Browning andChiappori [1] argued that the theory should not apply to that case: two indi-viduals have two utility functions, not one. For households, the individualchoice problem is compounded by a sharing problem. It turned out thatthey were right: on consumption data concerning singles, the symmetry ofthe Slutsky matrix was not rejected.III. Testing with household dataThen Browning and Chiappori built a theory for household data and testedit. We shall model two-persons households in a very simple way: two in-dividuals sharing the same budget constraint. Let U1(x1) and U2(x2) betheir utility functions. Individual consumptions x1 and x2 are not observ-able, but joint consumption x = (x1 + x2) is. The total earnings of thehousehold are w, and they share it in an unknown way, allotting w1 (p) tothe first and w2 = w−w1 (p) to the second. Then each one solves his/herown problem:maxx U1 (x) maxx U2 (x)px ≤ w1 (p) px ≤ w − w1 (p)Leading to the indirect utility functions:V1 (p) = max{U1 (x) | p′x = w1 (p)}V2 (p) = max{U2 (x) | p′x = w − w1 (p)}and to the equations:DpV1 (p) = −λ1 (p) (x1 (p)− Dpw1 (p))DpV2 (p) = −λ2 (p) (x2 (p) + Dpw1 (p))− 1λ1 (p)DpV1 (p)−1λ2 (p)DpV2 (p) = x1 (p) + x2 (p) = x (p) (2)IvarEkelandFall 2002 19Pacific Institute for the Mathematical SciencesWe now raise the question: given a vector field x (p) , when can wefind convex functions V1 and V2, and positive functions λ1 and λ2 suchthat the decomposition (2) holds locally? A necessary condition was foundby Browning and Chiappori, and proved to be sufficient by Ekeland andNirenberg [3]: the Slutsky matrix S (p) of x (p) should split into the sumof a symmetric, negative definite matrix, and a matrix of rank 1 :S (p) = Σ (p) + a (p) b (p)′ , with Σ (p) = Σ (p)′ > 0 (3)So household demand, although it does not satisfy the Slutsky condi-tion, satisfies a weaker condition, which is (3) in the case when the house-hold consists of two persons. Lo and behold, this condition is not rejectedby econometric tests conducted on collected data. I find it a most remark-able fact that people solve complicated systems of nonlinear PDEs simplyby taking care of themselves.IV. Testing with market dataConsumption data concerning households or individuals is difficult tocome by. It would be much easier to test the theory on market data, that is,the aggregate consumption of many individuals, which is readily found inmany available sales statistics. Let us again consider a simple model, con-sisting of N individuals, each one with his own utility function Un, andhis own wealth wn, resulting in an individual demand function xn (p). Weobserve the wn and the aggregate demand X (p) = ∑ xn (p).As above, we have:xn (p) = −1λn (p)DpVn (p)wn = −1λn (p)p′DpVn (p)Substituting, we get a system of K nonlinear PDEs for the Vn:N∑n=1wnp′DpVn (p)DpVn (p) = X (p)and, as above, we seek convex solutions. Chiappori and Ekeland [2] haveshown that such a solution exists (locally) for any analytic right-hand side.From the economic point of view, this is a negative result: any analyticmap X from RK into itself can be a market demand function, so thereare no conditions to test. From the mathematical point of view, this raisesanother question, to which I would very much like to know the answer:what about smooth, but not analytic, right-hand sides? To give a specificexample, can one find functions u (x, y, z) and v (x, y, z) such thatuxuz+ vxvz= f (x, y, z)uyuz+ vyvz= g (x, y, z)where the right-hand sides f, g are C∞? The question is open.References[1] M. Browning and P.-A.

Philippe’s tireless work for mathematicsduring his tenure as the Director of the Division of MathematicalSciences, has also had a substantial impact beyond the UnitedStates borders.From the Canadian perspective, Philippe’s leadership at theNSF will always be connected to the Banff International ResearchStation (BIRS).  When this station was proposed Philippe had theforesight to realize that it would provide an incomparable resourcefor the Mathematical Sciences community in North America, and indeed the world.Through their support of BIRS, NSF Director Rita Colwell, NSERC President TomBrzustowski, and Philippe set a new precedent for joint U.S-Canada scientific collaborations.BIRS will be one of the enduring legacies of Philippe’s tenure at the NSF.The recent renaissance and awareness of the Mathematical Sciences in North America owesa great deal to Philippe’s work at the NSF.On May 15, 2002 a celebration in Philippe's honor was held in the Great Hall of the NationalAcademy of Sciences in Washington, D.C.continued from page 4If you are an organizer or participant of anupcoming BIRS programme, be sure to checkout the website for the links to the Banff Cen-tre and its extensive programme of artistic ac-tivities, its very considerable athletic facilities(swimming pool, climbing wall, etc.) and otherlinks to the National Parks, shuttle services,accommodations for extending your stay, maps,and so on. You will also find that your work-shop has its own webpage.The location of BIRS in the lively artisticcommunity of the Banff Centre raises the po-tential for workshops that combine the normalfare of the mathematical sciences with otherparts of cultural world that makes up our soci-ety. One such example is a BIRS workshop onCreative Scientific Writing that will be heldaround Labour Day 2003. Each year we wouldlike to run a couple of events of this type. Ifyou are interested in creating a proposal thatcrosses boundaries between the traditionalmathematical/scientific culture and the any ofthe arts (music, dance, theatre, visual arts, me-dia, etc.), BIRS is certainly receptive.BIRS opens its doors for business on March15, 2003. It was in October 2000 that NassifGhossoub first began to travel around, sound-ing out how much enthusiasm there was for aNorth American answer to Oberwolfach, to besituated in the Canadian Rockies. The responsewas immediate and emphatic; Do it! But to doit, and to have actually done it (in just 2 years),that is another matter. And to have done it bycreating an international partnership with oneof the top mathematics institutes in America,and with the cooperation of scientific fundingagencies in United States, Canada, and Albertaas well as MITACS – this is more than wecould have dreamed at the time.To celebrate the remarkable achievement ofcreating this new institution there will be a partyon February 28 at the Banff Centre. This willbe a gala affair the combining of the Boards ofTrustees of PIMS, MSRI, MITACS, the Aca-demic Sponsors of MSRI, the Scientific Advi-sory Board of BIRS, and of course suitablerepresentatives of NSERC, ASRA, and theNSF  — all told some 150 people.BIRS website: http://pims.math.ca/birs/Open Letter to The Prime Minister ofCanada, The Honorable Jean ChretienThe Fields Medal is the highest recognition that the world mathematics community offers forresearch in mathematics, and in prestige it rivals the Nobel Prize (which is not given in mathemat-ics).  Unfortunately, few are aware that J. C. Fields was a Canadian, that the Fields Medal was aCanadian idea, and that the Fields Foundation is located in Canada. This is in sharp contrast withthe Nobel Prize which is usually announced and presented by the King of Sweden.Recently, the Norwegian Prime Minister, Mr. Jens Stoltenberg, has taken the lead by grantingUS$22 million to fund the Abel prize: a new international prize in  mathematics that is supposed toserve as the counterpart of the Nobel Prize for our discipline. This is in sharp contrast with thetoken monetary value of the Fields medal.In 2002, there may be an opportunity to change that:(1) to clearly identify Canada with the Fields Medal,(2) and to increase the monetary value of the Fields Medal.The International Congress of Mathematicians will meet in Beijing in August 2002. The Chi-nese President is expected to be present at the opening ceremony where the medals will bepresented. It is important that a very prominent Canadian—the Prime Minister, the Governor-General or the Minister of Industry—be present in Beijing to award the Fields Medals. It is also agood opportunity for the government of Canada to align the medal with the Nobel Prize byannouncing an appropriate level of funding.This is a unique opportunity to brand Canada as a leader at the highest level of internationalresearch, and to retain that branding through the continuing identification with the Fields Medal. Itis entirely consistent with the government’s goal of moving Canada up ten places in world R&D.It deserves to be seized and given much prominence at the highest level.Nassif Ghoussoub, Director, PIMSArvind Gupta, Director, MITACSRobert V.

Led by Dr. Huaxiong Huang, the projectis entitled “Mathematical and Computational Modelling of Semi-ConductorManufacturing Processes”.  The main goal of the project is to improve semi-conductor manufacturing through scientific modelling.  Many of the groupparticipants, the author included, were first introduced to a portion of thisproblem by Bill Micklethwaite of Firebird Semiconductor at the 5th PIMSIndustrial Problem Solving Workshop held in June 2001 in Seattle.The group consists of a handpicked international collection of researcherswith a variety of backgrounds and expertise.  This last May the group met forthe inaugural PIMS-MITACS crystal growth workshop that took place atUBC.

Sean Bohun, Penn StatePIMS held its 5th Annual Graduate Indus-trial Math Modelling Camp (GIMMC) atSimon Fraser University May 18–23.  At thecamp 60 graduate students from all overCanada, the US and even some from as far asEurope cut their teeth on some problems inIndustrial Mathematics presented by prestigiousacademic mentors.As usual the week begins when the mentorspresent a mathematical problem inspired froman industrial application. The students thenbreak into teams and spend 5 intensive daystrying to solve the problem. The mentor, whohas a good idea of how to solve the problem,acts as a gentle guide helping the students reachtheir goal. The objective is to prepare the stu-dents for the types of challenges they may facewhen they move out into the workforce. Also,many students are exposed to truely appliedmathematics for the first time. Finally, it is away of preparing for the PIMS IndustrialProblem Solving Workshop held the follow-ing week.Brett Stevens of Carleton University pre-sented a problem in software testing. The ideawas to apply combinatorics and statistical de-sign to devise the best possible set of tests fora piece of abstract software.  The studentsworked very hard devising combinatorial cov-erings of the space of possible input param-eters.Tim Myers of the University of Cape Townpresented a problem on heating an airplane wingin order to evaporate water before it freezes.His students made great progress in modellingand solving this challenging thin film problem.Chris Budd of the University of Bath pre-sented a problem where you use a prod to testfor the freshness of fish. His students werechallenged into building a mathematical modelthe fish prods response and attempting to inferwhat information on the freshness of the fishcould be retrieved from the data. FortunatelyProf. Budd came with some pre-made fish dataso that no fish had to be prodded during theinvestigation.Yongji Tan came all the way from FudanUniversity in Shanghai China to present a prob-lem applicable to the oil and gas industry. Thestudents were asked to investigate the resultsof a well log tool that measures the resistivityin the surrounding structure. The studentslearned a great deal about finite element meth-ods.Alexander Melnikov came from the Uni-versity of Alberta with some problems in fi-nancial mathematics. His problem attracted thelargest number of students who were interestedin learning about hedging and option in bothcomplete and incomplete market settings.Petra Berenbrink was a local mentor fromSFU. She brought her students right to the veryedge of research in the complex area of routingin ad-hoc networks. The students came up withmany new approaches and some counter-ex-amples to this very difficult problem.Brian Wetton from UBC challenged thestudents with a very complex problem in mod-elling a protein membrane of a fuel cell. Hisstudents did an excellent job of solving somevery difficult mathematics.This year the students had a unique oppor-tunity to present the results of the week’s workin the form of a poster at the MITACS-AGM.5th PIMS Graduate Industrial Math Modelling CampSimon Fraser University, May 18–23, 2002Contributed by Marc Paulhus, University of CalgaryFall 2002 23Pacific Institute for the Mathematical Sciences6th PIMS Industrial Problem Solving WorkshopUniversity of British Columbia, May 27–31, 2002Contributed by Marc Paulhus, University of Calgary and Ian Frigaard, University of British ColumbiaPIMS held the 6th Industrial Problem Solv-ing Workshop  (IPSW) at the University ofBritish Columbia in Vancouver on May 27—31.  About 100 people registered for the event,including the 60 graduate students who hadtaken part in the graduate modeling camp theweek before.  Faculty from as far away as SouthAfrica, Finland and China were also involved.Participants split up into six groups to attackthe industrial problems brought to the work-shop, spanning a broad range of applicationsand mathematical techniques.  Most of the in-dustrial participants were able to stay all weekthis year, and were actively involved in work-ing with the groups. A brief description of theproblems and some of the progress made isgiven below. More complete problem descrip-t ions may be found on the website,www.pims.math.ca/industrial/2002/ipsw/problems.html, and proceedings papers arenow being written by each group.Edmond Lou represented Capital Healthof Edmonton and brought a problem involvingautomating the process of analysis data from a3D laser scanner that is used to diagnose pa-tients with scoliosis. The current process, al-though good, relies on many manual user stepsto complete the analysis. The team was able toshow how some standard (and some not sostandard) image processing techniques couldbe used to fully automate the data analysis pro-cess. Further, Capital Health was interested inknowing if it was necessary to use the physicalmarker points that they currently place on thepatient’s back before the scanning process. Theteam was convinced, after looking at a largeamount of sample data, that the informationgiven by the marker points could not be re-trieved mathematically from the data, and henceare necessary.Kai Meunzer from Shell Canada came tothe workshop with an inverse problem: Givenseismic and magnetotelluric data, can we de-termine geological properties of the Canadianfoothill? After some discussion on the back-ground materials of both seismic andmagnetotelluric methodologies, the team real-ized that the best approach was to construct asimple one-dimensional 3-layer model to test ahybrid seismic-magnetotelluric approach byminimizing the weighted least square errors ofboth seismic and magnetotelluric data. Eventhough the team worked on this project wasthe smallest, each participant brought consid-erable expertise from various areas. With thehelp of Doug Oldenburg, (an expert in geo-physical inverse problems), Yongji Tan, (anexpert in inverse problems), and with the helpof two graduate students, it was found that thehybrid method works better than either seis-mic or magnetotelluric approaches. This wasonly true if appropriate weight functions werechosen. Kai Meunzer was very satisfied withthe progress made during the workshop andsome follow-up work after the workshop hasprovided further insight into the problem.Edward Keyes of Semiconductor Insightswas interested in an algorithm to automaticallystitch a large number of images of an integratedcircuit together in order to reconstruct the im-age of the entire circuit itself.  This problemattracted a large number of participants whoquickly broke into teams to test the many dif-ferent approaches that were suggested.  Themost straightforward approach, based on least-squares was implemented and tested during theweek and was found to be a significant im-provement over the current method. Other ap-proaches, based on graph theory, simulatedannealing and linear programming also showeda great deal of promise. It is clear that once thesmoke clears the company will have an algo-rithm that is a significant improvement overthe current techniques.Appearing in his second IPSW, BruceMcGee of MacMillan-McGee presented thefollowing scenario. One method of recoveringsoil contaminants is to electrically heat the soilwith various electrodes inserted into wells inthe ground. By injecting water into certain elec-trode locations and pumping fluids out of theremaining locations, the contaminants areslowly removed.  If the contaminants are actu-ally removed, as is intended, this processshould change the resistivity of the soil as itprogresses. For this reason, departures fromthe characteristic evolution of resistivity are ofparticular interest.  The workshop participantswere given the inverse problem of find the ac-tual resistivity,  given the response curve of thecurrent, (or indeed any other measurable data).Failing this, was it possible to localize wherein the domain any changes in resistivity oc-curred?  Because of the size of the group (7faculty and 9 graduate students), various as-pects of the problem were investigated.  Tounderstand the forward problem a sequence ofone and two-dimensional models were con-structed to determine (i) the time evolution ofthe temperature field when cold water is in-jected and (ii) the sensitivity of the model tosmall localized changes in the resistivity. Thesepreliminary investigations illustrated that an in-ternal transition layer is generated during thepropagation of the shock of injecting cold wa-ter, which persists in the steady state.  Further-more, the measured voltage between the elec-trodes is much more sensitive than the outflowfluid temperature to localized resistivitychanges.  Using these forward models as justi-fication, the temperature field was neglectedfor the inverse problem and an attempt wasmade to implement the generalized sensitivitytheorem in a square domain with a localizedresistance anomaly at its centre.  By combiningthe computed voltage field in the domain with-out the anomaly with a series of voltage mea-surements obtained with the anomaly in place,a picture of where the anomaly was locatedwas built up. Work continues on the problemspecifically in extending the analysis of the in-verse problem to a simple layered medium.  In-vestigations to increase the resolution of theinverse problem using an analytic Green’s func-tion and finite difference rather than finite ele-ment methods are ongoing.  Bruce McGee wasquite pleased with the progress made on theproblem and anticipates a predictive model thatcan be used onsite.

Sixteen undergraduate stu-dents in commerce, engineering, business,physics, mathematics, statistics, and computerscience were invited from across Canada tomeet industry executives and renowned aca-demics, and to explore graduate study oppor-tunities, and to work in teams to solve chal-lenging business problems.The focus of the workshop was a real-world case study competition, culminating withpresented a challenge to compute the closedform solutions to some very complex “pseudo”statistics.  The team for this problem consistedalmost entirely of graduate students, most ofwhom were new to financial mathematics.Nevertheless, the result was achieved and welook forward to seeing the full solution pre-sented in the report.In the areas of petroleum exploration andreservoir engineering, geoscientists use con-cepts from seismology to image the subsur-face and determine essential rock-physics prop-erties. Experimental conditions are typically inthe form of a seismic survey whereby mea-surements are made of a seismic wave travel-ing between source and receiver. Talisman En-ergy presented an inverse seismic ray problemthat sought to incorporate recent technologicaladvances in the determination of elastic moduli.In particular, with the development of three-component geophones it is now possible tomeasure particle displacement associated witha seismic wavefront at depth. Such an experi-ment, whereby sources are located at the sur-face and geophones are place within the earth,is called a VSP, (vertical seismic profile). Itwas hoped that pairing particle displacement(i.e. ,  polarization angle) with recordedtraveltime would lead to an in situ inversionfor elastic modulii requiring only a singlesource/receiver pair. Using concepts of asymp-totic ray theory and continuum mechanics theteam was able to formulate a system of eightnon-linear equations that could be solved forthe elastic modulii that were sought. Unfortu-nately, with the introduction of experimentalerrors, the system proved highly unstable andhad to be abandoned. However, with the intro-duction of some further, yet not overly restric-tive, assumptions, the team went on to formu-late a new system of four non-linear equations.Initial follow up work suggests the new for-mulation is reasonably stable under experimen-tal conditions.Apart from the mathematics, an enjoyablesocial time was had by all.  Mathematical mod-eling of industrial problems is an interactivesocial activity and many problems were dis-cussed well into the evening at Koerners pub.Proceeding from IPSW will soon be avail-able at www.pims.math.ca/publications/pro-ceedingsThe annual prize for the best “PIMS-slip”went to Fabien Youbissi for the followinggem: Receptionist at Gage: “Your name please?” Fabien: “Youbissi” Receptionist at Gage: “No, your name, not your university”Witnesses report that a few more repetitionsoccurred, before the light came on ...

Instead scientists solvethe equations numerically or use the results oflaboratory experiments to guide their intuitionin finding solutions.In its dedication to the training of highlyqualified personnel, each year the Pacific In-stitute for the Mathematical Sciences (PIMS)sponsors a fluid dynamics summer school atthe University of Alberta.  The two week longevent is attended by graduate students andsenior undergraduates from around the world.Each morning the participants attend lectureson a broad range of topics including wavesand turbulence, convection, physical ocean-ography and climate modelling.  The afternoonsare spent gaining hands-on experience runningnumerical simulations and performing labora-tory experiments which are designed tocomplement the lectures and which are adaptedfrom the lecturers’ current research.  At theend of the school the students give presenta-tions based on the results of their work.There are two other annual fluid dynamicssummer schools in the world, one at the Uni-The Fourth Annual PIMS Fluid Dynamics Summer SchoolUniversity of Alberta, July 28–August 9, 2002Contributed by Bruce Sutherland, University of Albertaversity of Cambridge, England and the other atWoods Hole Oceanographic Institution, MA,USA.  The PIMS Fluid Dynamics SummerSchool is unique in its emphasis on computa-tional fluid dynamics and computer-aided labo-ratory measurements.  Indeed, with its moderncomputational resources and its concentrationof expertise in experimental and numerical fluiddynamics, the University of Alberta is one ofthe few institutions in the world capable of run-ning a school which simultaneously exposesparticipants to theory, numerical and experi-mental methods.This year the Fourth Annual PIMS FluidDynamics Summer Schoolran from July 28 to August9.  The summer school wasfully attended by eighteenparticipants from Canada,England, Germany and theUnited States.  Core lectureswere given by John Bow-man (Turbulence Model-ling), Andrew Bush (Cli-mate Modelling),  PeterMinev (Computational FluidDynamics), Bryant Moodie(Wave Theory),  BruceSutherland  (Stratif iedFlows) and Paul Myers(Physical Oceanography).We had four invited lecturers: John Allen(University of Oregon) spoke on “CoastalOceanography”.

Stu-dents find projects to work on, they prepareposters and demonstrations, the public is in-vited to come and see what they have done,and a panel of judges awards prizes for projectsthat are deemed to be the best.A math fair is similar, but two importantdifferences set our concept apart. Althoughmathematics is extremely diverse, our math fairsconcentrate on just one aspect of the subject,namely problem solving, and our fairs are offi-cially non-competitive, so there are no awardsor prizes.  We have chosen to focus on prob-lem solving for several reasons. It is one activ-ity that is common to most of mathematics, it isfrequently an explicit part of the mathematicscurriculum and it encourages skills in studentsthat can be applied in all areas of their lives.The problems in this booklet are ones thatyoung students can solve and truly understandwith a reasonable amount of work. They willnot need a broad educational background, butthe problems are not simple and most will haveto think before solving them. The same is trueabout the people who visit the math fair eventhough they may be adults or students fromhigher grades. When the participants presenttheir problems, they will discover that the visi-tors need help to work through the solutions,and the presenters will gain the satisfactionand confidence that comes from helping moretalented or older persons.The interaction between the participants andthe viewers at a problem-based math fair canhave a profound effect on the poise, confidence,communication skills and patience of the par-ticipants.  The reason for our second differ-ence, that the math fair be officially non-com-petitive, is so that all students are encouragedto participate and benefit. If some students feelthey have little chance of winning they maydecline to join in or not put in a full effort.Even if a math fair is officially non-competi-tive, informal competition does occur.  The par-ticipants quickly recognize who among themare good problem solvers, who can explainthings well, whose presentations have the bestartwork, and which displays attract the mostvisitors. But this sort of competition is friendlyand constructive, and frequently leads to co-operative efforts among the participants.  Thefocus on problem solving and the lack of for-mal awards are the key parts to our concept of amath fair for children, but otherwise there aremany opportunities to creatively adapt the con-cept to a particular situation. We hope you willfind this booklet useful in organizing your ownmath fair and are looking forward to hearingfrom you about your experiences.PIMS/University of Alberta Math Fair, March 21, 2002Contributed by Ted Lewis, University of AlbertaHow often do you find grade school studentshappy to spend two and a half hours doingmathematics? This is what happened for about450 students from elementary and junior-highschools in the Edmonton area on Thursday,March 21, at the PIMS/U of A Math Fair.There were actually two parts to the activities—the fair itself which was presented by the stu-dents of the Math 160 class, and a problemsolving session conducted by Andy Liu.The math fair was non-competitive, and pre-sented mathematical puzzles for the visitors totry. The puzzles were very diverse, from river-crossing problems to the towers of Hanoi.Here’s one that was very popular (and it’s so-lution is not immediate even for us): Put 8hockey pucks in a straight line. The problem isto make four piles with two in each pile byjumping some of the pucks over the others.Each jumping puck must pass over exactly twopucks and land on a single puck. It doesn’tmatter whether the two pucks you are jumpingover are an existing pile of two or are sitting bythemselves. Spaces don’t count.After the students solved that puzzle theywere asked to see if they can start with 10 pucksand end with 5piles of two,or 12 pucksand end with 6 piles of two and so on. At leastone child figured out the recursion and showedhow to do it for up to 16 pucks.Among other things, Andy’s session in-volved “scientific origami”.  Unlike the mathfair, where the students moved from booth tobooth, Andy’s was a sit-down session. Theproblems were very challenging, and the suc-cess rate among the students was very high.The math fair is part of the curriculum forOn the way to the Math Fair.PIMS published the math fair booklet by Ted Lewis in the Spring. This is a major new resource for teachers and others interested in math fairsfor schools. It is based on the experience of the author and his colleagues over the past few years. It is a rich source of guidelines to organizingmath fairs, and to finding suitable problems puzzles and challenges.The booklet will shortly be available for free download in pdf format suitable for laser printing. Hard copies may be purchased from PIMSUniversity of Alberta for a nominal fee (US$10.00 for shipping and handling in North America, US$15.00 elsewhere).The New PIMS Math Fair Booklet by Ted LewisFrom the Introduction: the math fair booklet  by Ted Lewis, PIMS 2002.Vol. 6, Issue 228Pacific Institute for the Mathematical SciencesMath 160 and has significantly revitalized thecourse. This is the first time that the math fairtook place on campus instead of at individualschools. Moving the fair here was promptedby both the popularity of the fairs and associ-ated logistical problems of taking a Math 160class to a school away from the campus. Hold-ing it here solved some problems but raisedseveral others. Renee Polziehn from the uni-versity outreach center provided many usefulsuggestions.Shirley Mitchell and Lisa Haraba fromPIMS were invaluable in helping with the or-ganization of the fair. For the past few years,PIMS has sponsored the math fairs, and theresult is strong cooperative effort between ourMath Fair at Greater Vancouver Regional Science FairUniversity of British Columbia, April 4–6, 2002Contributed by Janet Martin, PIMS Education OfficerThe Math Fair project took place this year amidst the teachers’ job action.  Yet despite thisobstacle, ten projects were entered in the Computational and Mathematical Sciences cat-egory at the 2002 Greater Vancouver Regional Science Fair (GVRSF) and of these, twowere selected to attend the Canada-Wide Science Fair held in Saskatoon, Saskatchewan inMay 2002.  These students were Gabrielle Arden of Burnaby South Secondary School andRochelle Leung of York House School (pictured).PIMS gave the following awards.First: Rochelle Leung (York House): Decrypting the math behind cryptography and itsciphersSecond: Gabrielle Arden (BurnabySouth Secondary): Forecasting weatherwith neural networks, Frank Sun andWinnie Ho (Windermere Secondary):Matrices and cryptology, Harvey Zhang(Burnaby North Secondary): Inscribedtriangles in circles and ellipsesThird: Pearly Trinh and Elaine Lee(Windermere Secondary): RSA algorithmcryptology, Galina Meleger and KathrynCheng (York House): The golden num-berThe first prize winner received $200, the second prize winners $100 each and the thirdprize winners $50 each.Considering there were only tenprojects entered in the Computational andMathematical Sciences category, it is note-worthy that the GVRSF judges selectedtwo of these projects as part of the top tenprojects at the entire science fair.PIMS contributed $2500 travel moneyto send two winners to Saskatoon.At the Canada-Wide Science Fair,Gabrielle Arden won a Gold Medal and a$2000 scholarship to the University ofWestern Ontario in the Intermediate Com-putational and Mathematical Sciences cat-egory, and Rochelle Leung won a Bonze Medal and a $1000 scholarship to the Universityof Western Ontario in the same category. Congratulations to both students on their out-standing projects!department, PIMS, and the schools in Albertain promoting mathematics. Feedback fromschool teachers show that the math fairs widenthe children’s interest and perception aboutmathematics. The idea is spreading and mathfairs modelled after the Math 160 fair are in theworks for Going to the Math Fair, March 212002 Calgary, Vancouver and Ft.

Teams ofteachers from several Calgary-area schools wereinvited to a half-day workshop.  The focus ofthe workshop was on teaching mathematicsthrough explorations and investigations byworking through a number of mathematical ex-plorations, suggestions for introducing explo-rations to other teachers, organising and pro-moting a school math fair.The teachers returned to their schools armedwith Ted Lewis’ excellent booklet on how torun a math fair.  Sharon Friesen of GENA andIndy Lagu (PIMS Education Coordiantor,Calgary) made visits to the schools to workwith the teachers and students before the mathfairs.After the math fairs, the teachers were in-vited for another half-day workshop to talkabout problem solving, what worked and whatdid not with their fairs, and future steps.  Manyof the teachers admitted that they were worriedabout how successful their math fair would be,but none were disappointed, and all thought ofthe math fair as an unqualified success.  Themany parents who attended the math fairs werealso quite impressed.  In all, seven schools par-ticipated, and all expressed an interest in re-peating a math fair.  More information aboutthe math fairs (including lots of photographs)can be found at www.galileo.org/math/sumtalk/index.html.Dr. Friesen and Dr. Lagu are planning toinvolve 10 or 12 new schools in the projectnext year.Fall 2002 29Pacific Institute for the Mathematical SciencesCalgary Youth Science FairApril 10—13, 2002At this year’s Calgary Youth Science Fair thePIMS award went to Katanya Kuntz, a grade11 homeschooler from Alberta Distance Learn-ing.  Her project was called Quantum Physicsand Spectroscopy.  The objective of the projectwas to learn more about Quantum Physics andto test mathematical models of the atom (theBohr theory and the Quantum theory) for theiraccuracy in predicting and explaining the atomicuniverse.  Her Unified Hypothesis was “Spec-troscopic signatures, other atomic characteris-tics, and atomic phenomena can be accuratelypredicted and explained by a mathematicalmodel of the atom.”  She concluded that theQuantum theory is the best known model (sofar) that is extremely accurate in predicting andexplaining the atomic universe.Katanya Kunts and Gary Margrave infront of her project.PIMS ELMACON 2002Contributed by Heather Jenkins, PIMSThe fourth annual PIMS Elementary GradesMath Contest took place on May 25 at UBC.This contest is organized by PIMS underthe guidance of Dr. Cary Chien of David Th-ompson Secondary School in collaborationwith the BCAMT and volunteers from LowerMainland schools of all levels.  It is open tostudents in Grades 5 to 7 giving them a chanceto experience mathematics as an exciting sport.A total of 229 students competed in the con-test with 67, 80 and 82 in grades 5, 6 and 7respectively.  The format was the same as inprevious years.  There were 3 rounds, and thewritten part came first with the Sprint and Tar-get rounds.  The top 10 from these rounds wenton to the Countdown round where the students“duelled” starting with the 9th and 10th.  Thewinner of that contest then went on to “duel”with the 8th place holder.  So the person whoranked 10th had the potential of winning thecontest by beating the 9 people ahead of him/her one by one.  The duelling consisted of an-swering math questions against the clock andsounding a buzzer.The top 10 in each grade received a t-shirtand medal. The top 3 also received a trophyand an electronic calculator donated by Sharp.Certificates of participation were available forall students on the day.Top 10 winners in each grade are as follows:Grade 5: 1.

We now feature shortprofiles of the winners of the last 7 months of the contest.Back in July when Florence Nightingale was featured, the winner was Alain Goulet of Victoria,BC.  He is a 46 year old father of 4 who is studying towards a B.Sc. in Mathematics at the Universityof London through their External Programme.  Most of his career so far has been in the financial/accounting field, which he hopes to change when he is ready to start his graduate studies in math-ematics.  Recently he has also become interested in astronomy.In August, the month we featured Maria Goeppert Mayer, the winner was Stefanie Smith ofKingston ON.  She is 24 year old student at Queen’s University working on a Ph.D. in Computa-tional Chemistry.  Her inter-ests include camping, curlingand skiing.  She found outabout the contest from afriend, and she thinks that it’sa great way to learn about fa-mous women in science andmath.Jordan Bemmels  ofRichmond, BC won the Sep-tember Emmy Noether con-test.  He was 14 years oldand in Grade 9 at the time,and he found out about thecontest from his mathteacher.  He said “I think thatthe contest is a great way foreveryone to learn more about“Women in Mathematics,”and mathematics in general.Learning mathematics can be useful throughout life, so this contest is very practical for nearlyeverybody.”  He is interested in geography and the humanities, plays the piano and trumpet, androller-blades.In October the winner was Lichung Jen also of Richmond, BC, who works at Minerva DatabaseMarketing Consultants Ltd.  The contest featured Sofia Kovalevskaya. Lichung is 40 years old andfound the contest very interesting.Caroline Herschel appeared in November and the winner was Wayne Chevrier of Langley, BC.He was also a winner of the Mathematics is Everywhere contest.The December winner was Michelle McGinty of Waterloo, ON and that month we featuredMaria Gaetana Agnesi.  She is 39 years old and is a University Waterloo Mathematics Graduate andteaches secondary school mathematics at Waterloo Collegiate Institute.  Michelle said “I think whatPIMS is doing is fantastic: your semi-annual Pi in the Sky  publication, your visits to elementary  andsecondary schools and your contest.  I have all of the posters of this year’s contest posted in myclassroom.  I have some of last year’s bus posters that were sent to me posted on my classroomwindows.  They are wonderful,  the posters initiated a great deal of discussion and problem solvingby my students.”Emilie de Breteuil concluded the contest in January and Wendy Bennett of Victoria, BC, was ourfinal winner.  She is 51 year old mother of three children who has degree in Political Science.  Shelists her main interest as a fascination with people.  Her middle son, Andrew, is a math student andshe found out about the contest through him.To find out more about these women see www.pims.math.ca/education/2001/women.The New Issue of Pi in theSky MagazineThe fifth issue of the PIMS educational maga-zine Pi in the Sky came out in September2002.
