In 5 shortyears, PIMS’ scientists have collectively con-ceived of, and built an entity that has galva-nized the mathematical community. The in-stitute is now recognized world-wide as aneffective new model for the mathematical sci-ences: one that addresses simultaneously theimperatives of research, education and tech-nology transfer, and one that was able to unitea diverse community of many institutions overa geographically challenging area.PIMS’ early successes re-invigorated theCanadian mathematical science communityand stimulated its institutions. The institute’sproactive approach to industrial and educa-tion outreach, and its use of modern commu-nication and dissemination tools, contributedto changing the culture, to erasing outdatedperceptions and to increasing mathematicalawareness. PIMS’ energetic and vocal effortson behalf of the mathematical sciences led toa re-affirmation of their key importance,whether in K-12 school programmes, or forleading edge Canadian R & D efforts.Through a series of bold national and in-ternational initiatives (the MITACS network,the Banff International Research Station,the Pacific Northwest Partnership and thePacific Rim Initiative), PIMS has raised theprofile of Canadian research throughout theworld. By developing key partnerships, PIMSmultiplied the opportunities and attracted sub-stantial investments from industrial, provin-cial, federal and foreign sources in supportof Canadian-led research.Dr Tom Brzustowski, President NSERC:“The hallmark of a good idea is that somany people find it obvious once it has beenmentioned - obviously!” Dr Rita Colwell, Director of NSF:"BIRS underscores how international co-operation adds up to more than what anynation could accomplish alone.”Dr Brzustowski’s and Dr Colwell’s speeches are on pages 4-5.Banff  Station LaunchedOn September 24, 2001, the governments ofAlberta, Canada and the United States an-nounced the establishment of a new interna-tional mathematical research facility in Banff,Alberta. The Banff  International ResearchStation for Mathematical Innovation andDiscovery (BIRS) will annually host  thou- please see “Banff Station” on page 25sands of top international scientists and re-searchers for intense workshops, collabora-tive research efforts, and training sessionsacross the entire spectrum of pure and ap-plied mathematical sciences.Vol. 6, Issue 12 Pacific Institute for the Mathematical Sciencescontinued from page 1A Blueprint for the Future of PIMSTo connect and cement a strongresearch basePIMS is founded on the high-quality com-munity of mathematical scientists present atits participating universities. To nurture thiscommunity as it takes on a leadership posi-tion in society and in the world’s scientificenterprise, is the primary aim of PIMS. Thisgoal has led our institute to assume a role thatis both unique and ambitious in CanadianScience.PIMS Collaborative Research GroupsIn what is now its second phase of devel-opment, PIMS is embarking on a plan that willcreate and support collaborative multi-univer-sity teams of mathematical scientists. The ob-jective is to build upon our newinter-university networks anduse them as nuclei for provid-ing global leadership, and forgenerating and sustaining thescientific programming of PIMS in the yearsto come.The PIMS’ Collaborative Research Groups(CRG) are vehicles for networking betweenuniversities and for creating a research basethat substantially enhances training pro-grammes at all levels. The CRGs directly ad-dress the problems of retention and recruit-ment of faculty and give young faculty an ef-fective network for the development of theirresearch programmes. CRGs will also providescientific leadership at the Banff InternationalResearch Station (BIRS) and some will havethe potential to lead industrial projectsthrough the MITACS network. They will buildon existing links between the researchers ofWestern Canada and the US Pacific Northwest(PNW), thereby opening a new era of scien-tific collaborations between the two countries.PIMS has identified 32 potential CRGswithin its community. While some are alreadywell established and structured, in most casesthey are just forming. They fit into 5 broadresearch areas to which PIMS is strongly com-mitted: Fundamental Mathematics, AppliedMathematics, Mathematical Biology andMedicine, Statistical Sciences, and Theoreti-cal Computer Science.Periods of Concentrated ActivitiesTo provide the CRGs with appropriate re-sources, they will be dovetailed with a newPIMS programme supporting concentrated ac-tivities in 5-10 research areas each year. Theprogramme, run on a competitive basis, willsupport multi-site activities of selected re-search groups in a particular field over a 1-2year period of concentration. These periodsare designed to promote longer term, multi-event interactions for CRGs at participatinguniversities, in tandem with national and in-ternational collaborators and visitors. In itsperiod of concentration, a CRG will receivepriority from PIMS for (i)  thematicprogrammes, (ii) workshops at BIRS, (iii) fo-cussed research groups at BIRS and otherPIMS sites, (iv) Postdoctoral fellowships, (v)visiting distinguished chairs,and (vi) PNW seminar series.Additional support is expectedfrom partnerships (NSF, Perim-eter Institute, AIM, Clay Insti-tute, etc.) as well as teaching releases fromparticipating departments.With the above initiative, PIMS is creat-ing new ways for its scientific programmesto be driven by its member scientists and en-couraging grass-roots generation and long-term planning of its activities. It is also pro-viding its researchers with means to assumeleadership on the national and internationallevel. It is promoting partnerships between itsuniversities and facilitating the collaborativeeffort of its Canadian and US researcherswhile generating new opportunities. The ini-tially selected periods of concentration, andthe main coordinators of their CRGs are:Give me a place to standand I will move the earth.—ArchimedesTo build on PIMS’ national andinternational initiativesThe impact of PIMS goes far beyond thestrong roots planted in its community.Banff International Research StationIn partnership with MSRI, PIMS haslaunched a major international research ini-tiative in Banff. This unique joint Canada-USstation,  supported by NSF, ASRA andNSERC’s MFA Programme, also calls for aserious commitment of the PIMS budget. An-nually, more than 1700 mathematical scien-tists from around the world are expected toDr Nassif Ghoussoub, FRSCUpcoming Periods ofConcentration at PIMS:Inverse problems and applications, 2003Main Coordinators: G.

PIMSis committed to meeting such requests fromthe two universities in Saskatchewan. PIMShas also recently initiated a new comprehen-sive plan to address and support further theneeds of the mathematical science commu-nity in Atlantic Canada.PIMS is committed to provide additionalsupport for the mathematical sciences in thePrairies and Atlantic Canada, and to assist ingarnering matching funds from their univer-sities and provincial governments.To enhance PIMS’ distinctivelyinnovative programmesA highly interdisciplinary programmePIMS is committed to programmes thatbring together groups from disparate disci-plines (Math Economics and Finance `98,Mathematical Biology `99, EnvironmentalFluid Dynamics ` 01, Industrial Statistics ` 02).Besides distinguished mathematicians, theseprogrammes often included Nobel laureatessuch as J. Mirrlees, D. Huxley, and the lateM. Smith.PIMS is developing a 3-year programmeon “Mathematics and Multimedia” involvingmathematicians, statisticians, computer sci-entists and electrical engineers. Imaging andVision in 2003, Speech and Wireless Com-munication in 2004, and Mathematics, Com-puter Graphics and Human Computer Inter-action in 2005.PIMS commitment to trainingCommitment to training is reflected by themultitude of summer schools, training campsand orientation workshops that it runs for thebenefit of graduate and senior undergraduatestudents. The PIMS’ Schools in Environmen- please see “Future of PIMS”  on page 25participate in the Station’s activities. BIRS’2003 programme involved a competition be-tween 118 proposals for the 40 weeks avail-able. Among the selected workshops, 17 hadlead organizers from Ontario universities, 13from BC, 10 from Alberta, 6 from Quebec, 2from Saskatchewan and 2 from AtlanticCanada. BIRS is a truly national initiative anda remarkable continental resource.PIMS is committed to the further develop-ment of BIRS. It will continue to encourageand urge its sister Canadian institutes into afull scientific and financial partnership inBIRS. In particular, the institute is lookingfor the means to support travel costs of gradu-ate students and PDFs, to expand the pro-gramme to 48 weeks per year and to preparea solid funding base, in anticipation for along-term partnership with NSF and ASRA.The Pacific Northwest PartnershipIn 2000, the University of Washington be-came a major partner involved in all aspectsof the operations and management of PIMS.This unprecedented partnership has openedup a whole new era of scientific collabora-tions between the mathematical communitiesof the two countries. PIMS currently supportsthis collaboration through its sponsorship ofthe 12 PNW seminars and other joint activi-ties.PIMS is committed to developing furtherthis partnership, in collaboration with theNSF, with the PNW universities and with theUS mathematics Institutes. Joint activities in-clude: Focussed Collaborative ResearchGroups with the NSF, joint summer graduateschools with MSRI, and a joint Canada-USindustrial Mathematics programme in collabo-ration with the Minnesota-based Institute ofMathematics and its Applications (IMA).The Pacific Rim InitiativeTogether with other institutes in China, Tai-wan and Japan, PIMS is developing scientificlinks throughout the Pacific Rim countries.Jointly they organize major Pacific Rim sci-entific events (Hong Kong `98, Beijing `99,Taipei `01, and Vancouver `04). The PIMSmini-programme on Frontiers in Mathemati-cal Physics is a joint initiative with the Wa-terloo-based Perimeter Institute and the Ko-rea-based Asia Pacific Center for TheoreticalPhysics (APCTP). The three partners are againtal and Industrial Fluid Dynamics, theSchools in Mathematical Biology for SeniorUndergraduates, the Graduate IndustrialModelling Camps, the PIMS-IAM-CSC Se-nior Undergraduate Modeling Workshops,the PIMS’ Graduate Information Weekendsand PDF Conferences are run on an annualbasis. Students are invited from every part ofCanada to participate, with all expenses cov-ered by PIMS. Others come to the summerschools at their own expense from as far awayas Australia and New Zealand.PIMS also sponsors Canadian student par-ticipation in US hot-topic workshops such asthe recent one on Statistical Genetics andComputational Molecular Biology at theUniversity of Washington. In the same spirit,PIMS will host the 2002 MSRI summerschool on Computational Number Theory.PIMS will partner again with the NSF on vari-ous Pan-American Advanced Studies Insti-tutes: Dynamical Systems, Edmonton 2002;Inverse Problems, Santiago, Chile 2003.PIMS will develop new graduate summerschools and training camps in emerging ar-eas: Mathematical Genomics, Finance, Cryp-tography, Quantum Computing and other ex-citing areas.A modern approach to communicationand disseminationPIMS is also a pioneer in live web castingof major scientific events, and lectures by itsdistinguished scientists and visitors are nowavailable over the internet using on-demandstreaming video. PIMS is the only Canadianinstitute to offer such services to the world’sscientific community; it will continue to re-fine and expand these services.A success story for NSERC’sinvestment in researchNSERC’s $630K annual investment inPIMS is about a quarter of its support for the3 math institutes. It is nevertheless the cor-nerstone of an operating cash budget for PIMSthat exceeded $3.3M in FY 00/01 including$1M in matching support by its participatinguniversities and by the governments of Albertaand BC. This also includes $1.2M in cashcontributions from 32 private sector partners,Vol. 6, Issue 14 Pacific Institute for the Mathematical SciencesLadies and Gentlemen:If I may begin, Rita, with a personal request toyou: I would ask you on behalf of the entirestaff of NSERC, the Natural Sciences and En-gineering Research Council of Canada, to con-vey to our colleagues at the NSF, to the Ameri-can mathematics community, and to the peopleof the United States our heartfelt regret and ourprofound outrage at the event of September 11.I am very glad, as Nassif has already indi-cated that he is, that the eventtoday was not postponed or can-celled, because to have post-poned it or cancelled it wouldhave given a victory to the ter-rorists. They might never haveknown of it, but we would haveknown.Let me now move on to themost important thing that I have to do here. Ihave to read the magic words which make itofficial, and here they are. The Natural Sciencesand Engineering Research Council of Canadais contributing $1.5 million towards the opera-tion of BIRS from the year 2003 to the year2006.Now, we are here to celebrate a hugely im-portant event. It is hugely important not just forthe participating organizations, but for our na-tions, and for mathematics in the world.Let me begin by congratulating PIMS, MSRI,and MITACS. (I’ll stick with the acronyms, aslife is too short to spell them all out.) Let mecongratulate these three organizations for theirintellectual involvement and their promise todeliver the fruits of this superb internationalcollaboration.Let me also congratulate the funding part-ners. Let me congratulate the National ScienceFoundation of the United States. You heard inthe remarks of Dr. Colwell the extensive under-standing of the importance of mathematicswhich has driven their decision. And let me con-gratulate the Province of Alberta where BIRSis located. This is a province which, in my opin-ion, really does have its act together when itBut BIRS is also im-portant in another way.It puts the seal of rec-ognition by the fundingagencies on the waythat mathematicians doresearch: the face to face contact, the debate ofideas, the closing of dead ends — perhaps inthe presence of those who might have contrib-uted to paving them in the first instance, the op-portunity for people to change their minds, andthe excitement of recognizing a really new de-velopment and the ability then to go off withcolleagues and immediately talk about it somemore. All these aspects of working together ina setting like BIRS are hugely important. Math-ematicians assembled in an environment con-ducive to intellectual creativity will produce agreat deal.Let me finally come to something that I havebeen saying for quite a little while, and fre-quently — maybe even weekly. It is more of amatter for generalists thinking about mathemat-ics than it is for mathematicians. I really do be-lieve that mathematics has been the languageof high technology. And I also believe that math-ematics is becoming the eyes of science, help-ing scientists in all fields drink froma fire hose of data. But for math-ematics to function in this way, asthe language and as the eyes, andas the many other things that math-ematics is yet to become, there isneed for continued effort to expandand strengthen the foundations of mathematics— the work of basic research in mathematics.With that, let me conclude by congratulat-ing one more person, as the focus now shiftsfrom Nassif to Bob Moody. Let me congratu-late Bob Moody on becoming the research di-rector of BIRS. I think BIRS is very lucky tohave Bob Moody; I think Bob Moody is verylucky to have BIRS. This is a hugely importantinternational effort which will be important forCanadian mathematics, for mathematics in theUnited States, and ultimately for mathematicsin the world. I congratulate all who participatedin creating it. I thank our funding partners and Iwish everybody success in the years to come.Thank you very muchRemarks of Dr Tom Brzustowski,President, NSERCJoint Press Conference for the Banff International Research Station for MathematicalInnovation and Discovery, Banff, Alberta, September 24, 2001"Let me congratulatePIMS, MSRI and MITACSfor their intellectual in-volvement and their prom-ise to deliver the fruits ofthis superb internationalcollaboration."“Mathematicians inan environment con-ducive to intellectualcreativity will producea great deal.”comes to science and engineering research, andBIRS is yet another illustration of that.The hallmark of a good idea is that so manypeople find it obvious once it has been men-tioned — obviously! Why not?! You know thatOberwolfach has succeeded for many years.Why not, by way of developing a partnershipin research in mathematics in North America,set up something that would be at least as good,and maybe far better? And so it was done - on afast track and with quick decisions. Somethingwas done that would not havehappened, could not have hap-pened, without the vision, theenergy, the tenacity, and the lead-ership of one person, and that ofcourse is Nassif Ghoussoub.When I think of the manycontributions Nassif has made inmathematics, I know they in-clude some quite decent papers on partial dif-ferential equations. (I do look at Nature Nassif.I’ve seen your stuff.) Quite apart from that, hiscontributions as a leader in organizing math-ematical activity in Canada havebeen extraordinarily important.And now we see the leadershipstretching to international collabo-ration, and we welcome that.Now I should mention, perhapsfor the benefit of our American col-leagues rather more than the Canadian col-leagues who are already convinced of this, justwhy this is such an important event. It is thenext step in the emergence of Canadian math-ematics into the prominence that it deserves. Ca-nadian mathematicians have been good for avery long time. They have been very good, andwe have many outstanding individuals, but Ca-nadian mathematics in the corporate sense hasbeen achieving the deserved prominence onlyvery recently. The three institutes now active,CRM, Fields and PIMS, the Network of Cen-tres of Excellence MITACS, are all contribut-ing to that prominence. And today the interna-tional partnership that produced BIRS adds toit as well.Winter 2002 5Pacific Institute for the Mathematical SciencesGood afternoon, everyone. I am Rita Colwell,director of the U.S. National Science Foun-dation, and it is a great pleasure to take partin this ceremony — really a “virtual ribbon-cutting” — today.Our event connects two nations, the UnitedStates and Canada, exemplaryneighbors who have always cher-ished peace between each other. Inthat tradition, today we inauguratean enterprise that represents the bestof the human spirit.Following the tragic attacks onthe United States two weeks ago,this event today lifts our spirits as itsymbolizes our joint endeavor topush back the frontiers of knowl-edge. We have called today’s event “Close Par-allels”—a mathematical metaphor evoking thesteadfast closeness of our nations.The National Science Foundation supportscutting-edge science and engineering across therange of disciplines. We always strive to inte-grate research and education, really two facesof the same coin. We invest in the very best ofthe future, the fundamental research whose ul-timate outcome no one can foresee. Mathemati-cal research is an ideal example of such fertileground for far-reaching investment.Today NSF is very pleased to announce anaward to the Mathematical Sciences ResearchInstitute—MSRI. The award of $1.27 millionover four years will support United States’ par-ticipation at the Banff International ResearchStation for Mathematical Innovation and Dis-covery. The research station in the CanadianRockies in Banff will provide a spectacular set-ting for intensive mathematical research, whenit opens in 2003. The station is a project of bothour nations, led by the Pacific Institute for theMathematical Sciences in Vancouver, BritishColumbia, and MSRI, which I’ve already men-tioned, located in Berkeley, California.I cannot resist quoting the director of thePacific Institute, Nassif Ghoussoub; he said thatthe Banff Centre will enable visitors to “live,Remarks of Dr Rita Colwell,Director, National Science FoundationJoint Press Conference for the Banff International Research Station for MathematicalInnovation and Discovery, Arlington, Virginia September 24, 2001eat and breathe mathematics.” (I have to say thatsounds like a very nourishing diet—talk about“brain food!”)Our NSF contribution joins Canadian sup-port that will be described by our Canadian part-ners today. The NSF award will help supportthe travel and living expenses of par-ticipants in the research station’s pro-grams, especially those from theU.S. I should emphasize that our Ca-nadian colleagues and funding agen-cies have taken the lead in bringingthe Banff Centre into being. Thisactivity underscores how interna-tional cooperation adds up to morethan what any nation could accom-plish alone.Every important question of science and en-gineering is under study by re-searchers in nations around theworld. The mathematical and sta-tistical communities of the UnitedStates are at the forefront in en-gaging their counterparts abroad.International connections in mathematics areimportant throughout a career in science. In Juneof this year, NSF helped to support the Interna-tional Mathematical Olympiad, a competitionthat brought talented young people from morethan eighty countries to Washington, D.C. forthe annual event that was first held in Romaniain 1959. It was a rare privilege for us to host theOlympiad in the U.S. However, every year, NSFhosts the U.S. Olympiad team in Washington tohonor their achievements.Our investment in the Banff Center is tan-gible proof of the vital and growing role of themathematical sciences in all of science and en-gineering. I would like to show a few slides now,to illustrate this fundamental importance ofmathematics.E.O. Wilson writes that “...mathematicsseems to point arrowlike toward the ultimategoal of objective truth.” Indeed, mathematics isthe ultimate cross-cutting discipline, the spring-board for advances across the board. Mathemat-ics is both a powerful tool for insight and a com-mon language for science. A good example, pic-tured here, is the fractal, a famous illustrationof how inner principles of mathematics enableus to model many natural structures. Cosmolo-gists are beginning to draw an awesome por-trait of the structure of the universe—usingmathematics as the medium. On the other endof the scale, particle physicists sketch quantumphenomena, again with mathematics as theirbrush and palette. In the realm of climate, ourability to predict El Niño—the irregular shiftsin ocean and atmospheric conditions—is a su-perb example of where mathematics and com-puting have brought us. The meeting of math-ematics and medicine augurs well for discov-ery on many fronts. Mathematics and complex-ity theory, for instance, give insight into the hu-man heart. The top pictures are computer simu-lations of the electrical activity in a normal heart.Below are abnormal patterns, or fibrillation.Mathematicians are investigating why some pat-terns of electrical stimulus are better at elimi-nating fibrillation. Mathematics and biologytransform each other. The information scienceof life edges ever closer to electronic informa-tion science. Advances in under-standing life may lead to newmodes of computing, notably bio-logical computing.To strengthen the mathemati-cal foundations of science and so-ciety, the National Science Foundation has pro-posed a new priority area. We seek to advancefrontiers in three interlinked areas: fundamen-tal mathematical and statistical sciences, inter-disciplinary research involving the mathemati-cal sciences, and mathematical sciences educa-tion.I show this final slide as a mathematicalmetaphor. Fractal sets like we see here can beused to build computer models of clouds, plants,the surface of the sea, even networks of bloodvessels. Yet, mathematics also transports us be-yond the practical, into the realm of the imagi-nation and art. A coming together of brilliantimaginations for a higher purpose will be a hall-mark of the Banff Centre.We look forward to an inspiring and long-lasting engagement among our mathematicalscientists, our Canadian colleagues, and othersfrom around the world, in a superb environmentfor communication and collaboration.“In that tradition, todaywe inaugurate an enter-prise that represents thebest of the human spirit.”Vol. 6, Issue 16 Pacific Institute for the Mathematical SciencesReport on the Banff International Research Stationby Robert Moody, BIRS Scientific DirectorAfter the glossy events around getting BIRS offthe ground and the official launch of BIRS byNSERC’s President (Tom Brzustowski), NSF’sDirector (Rita Colwell), and the Chair ofASRA’s Board (Robert Church) on September24, it seems that we are in for a long wait untilwe actually begin the workshops at BIRS inMarch 2003. Nonetheless there has been a lotof BIRS activity going on. Most importantly the2003 competition for BIRS events has takenplace and we now have a full slate of workshopsin a dazzling array of different areas, as well asa fairly full parallel programme of FocusedResearch Groups and Research In Teams.The Evaluation of the BIRS 2003ProgrammeThe Call for Proposals for workshops atBIRS in 2003 was very enthusiastically re-ceived, resulting in 108 proposals. The overalllevel of proposals was outstanding, so much sothat the BIRS Steering Committee was sorelytempted to go ahead and accept 20 or more ad-ditional proposals for 2004. To sort their waysthrough this abundance of riches, the variouscommittees were guided in the first instance bythe principle that BIRS has to be inclusive ofall the mathematical sciences and that each yearits programme should provide a broad samplingof these. Thus the proposals were broken downinto some 22 areas, and within each area theproposals were evaluated and compared againsteach other. To the extent that these areashad worthy proposals (and they all did!) thecommittee then made sure that they wererepresented and that no area was grosslyover- or underrepresented. Not surprisinglymany really fine proposals fell by the way-side in this process. By the way, the BIRSSteering Committee made a decision earlyto eliminate any proposal that was closelylinked to any of its members. This elimi-nated a number of excellent proposals, butwe believe this was necessary for the integrityof the process.It may be useful for future proposers to notethe features the committees found themselveslooking for in trying to make their selections:• the proposal should be well-focused;• the set of proposed applicants should berealistic and should be logical to the coherenceone group. However, the idea of making somemore ambitious programmes into 7-day work-shops was accepted as an alternative.Also half-workshops (20 people for 5 days)were certainly welcome as a way to improvethe number of different groups that could behosted in a given year.It is good to reiterate here the fact that therewere many fine proposals that satisfied all thesedesiderata and still could not be accepted forlack of available weeks. We certainly wish toencourage people not to give up! BIRS will run,we hope, for many years, and there will be newopportunities. And PIMS is still pushing aheadto fund 8 more weeks each year at BIRS!The Other  Programmes at BIRSWe also had about fifteen proposals for theother side of the BIRS programme: Focused Re-search Groups and Research in Teams. Thesewere all very worthwhile proposals and it waspossible to satisfy all these requests, in-cluding hosting the Canadian Math-ematical Olympiad Team for 2 weeksin the summer of 2003. In the off-months (March, April, October, No-vember, December) of 2003 there is stillavailable space for such activities. Thereis also lots of space for 2 day events(Friday/Saturday). Submissions forthese events are still welcome and canbe made via the BIRS websitewww.pims.math.ca/birs.BIRS is also open to the concept of SummerSchools. However, since they come with a sig-nificant additional infrastructural and organiza-tional needs, these programmes should be co-ordinated directly with PIMS and MSRI. Pro-spective proposers should start by contactingthe appropriate institute director.and goals of the workshop;• the workshop ought to be sufficiently in-novative or sufficiently timely that holding ithas significant potential to make a difference tothe subject;• the organizers (at least some) should beof recognized stature;• the proposal should be written carefully,placing the above points clearly in the contextof the present state of the subject.A number of proposals were rejected for be-ing too diffuse, attempting to cover too manyareas at once, for not having a coherent set ofparticipants, or for not making a convincing ar-gument that they were different from any num-ber of similar events elsewhere.Beyond this there are other points, whichthough they were not of primary importance,still were on the minds of the committee.• The committee would like to see eachworkshop make some effort to involve youngand emerging talent in the form of post-docs oradvanced graduate students.• It is always good to keep in mind the ap-propriate representation of women in the list ofparticipants.• Priority will be given to those workshopsthat promote Canada - US research collabora-tion. Therefore, we would like to see that eachworkshop has at least one organiser from a Ca-nadian institution and one from an instution inthe United States.Some proposals attempted to link themselveswith back-to-back Focused Research Groups,or to pair themselves with other workshop pro-posals.

All incoming pro-posals are placed in one master file and all 27members of the BIRS Scientific Advisory Board(SAB) are invited to provide their written evalu-ations on-line on any proposal they wish to com-ment on.In addition, each proposal gets reviewed bytwo members of the SAB, assigned by the Sci-entific Director according to expertise in thesubject area. In some cases, external refereeingwas also solicited.All available information goes to the scien-tific panels of PIMS (resp., MSRI) who havethe responsibility to select 12 (resp., 6) BIRSproposals of interest to their own scientific pro-grammes from this file. The BIRS ScientificSteering Committee finishes off the selectionprocess choosing another 22 workshops, basedon the recommendations of its Scientific Advi-sory Board and on the input of the MITACS Sci-entific Director (for at least two weeks of in-dustrially oriented workshops).The PIMS ProposalsAs mentioned above, the PIMS ScientificReview Panel has the responsibility to select 12of the full set of proposals in the master BIRSfile. What constitutes an appropriate BIRS work-shop proposal for the PIMS Scientific ReviewPanel?First, it has to satisfy all criteria of excel-lence and innovation that are required by theBIRS evaluation process. In addition, they haveto be compatible with the PIMS scientific, in-dustrial and educational programmes, as dic-tated by the provincial funding sources for theinstitute and of BIRS.Priority is given to events that fit into otherparallel PIMS activities – particularly the Gradu-ate Industrial Modelling Camps, the PIMS newprogramme supporting Periods of Concentra-tion for Collaborative Research Groups, theThematic Programs, as well as various educa-tional activities. Beyond that the proposalsshould also have a strong connection to groups,strengths, or on-going activities within the PIMSparticipating universities in Canada and in theUS. For 2003, one week has been reserved forthe IMA-PIMS Graduate Industrial ModellingCamp and another one has been left open toallow for the inclusion of a “hot topics” week.Focused Research Groups (F) / Research in Teams (R) / Summer Schools (S)Banff International Research Station - 2003 ProgrammeFive Day WorkshopsVol. 6, Issue 18 Pacific Institute for the Mathematical SciencesThree PIMS Prizes for research, educationand industrial outreach were awarded at thePIMS Banquet held at SFU’s  Harbour Cen-tre Campus on December 1.The PIMS Research Prize is selected bythe Institute’s Scientific Review panel whichconsists of: David Boyd, Gordon Slade, NickPippenger (UBC), Alistair Lachlan (SFU),Bob Moody (U of A), Ian Putnam (UVic), RonGraham (San Diego), Dan Matkowski (Chi-cago), David Brillinger (Berkeley) and GangTian (MIT).The 2001 PIMS Research prize has beenawarded to Kai Behrend. Kai studied math-ematics at the University of Hamburg gradu-ating in 1983. After a master’s degree at theUniversity of Oregon and a Diploma at theUniversity of Bonn, he received his Ph.D. atthe University of California at Berkeley in1991, under Arthur Ogus.  His thesis  was onthe “Lefschetz Trace Formula for theFrobenius Morphism of an Algebraic Stack”.Kai was a Moore Instructor at MIT from 1991-1994 after which he joined UBC.Yuri Manin writes: “Partly in collaborationwith Barbara Fantechi, Kai produced the firstever algebraic geometric construction of theKontsevich virtual fundamental class and gen-eral Gromov-Witten invariants for arbitrarysmooth projective algebraic manifolds”.Kai’s construction has provided a key stepin the understanding of Gromov-Witten in-variants and made possible some of the deep-est work so far in enumerative algebraic ge-ometry.Kai is also regarded as one of the world’stop experts in the burgeoning area of alge-braic stacks.  Fields medalist  MaximKontsievitch writes: “The work of KaiBehrend is of the highest level and is abso-lutely fundamental in algebraic geometry”.Kai Behrend has also received the 2001Coxeter-James prize of the Canadian Math-ematical Society.The PIMS Education Prize for 2001 isawarded jointly to two very dedicated indi-viduals: Dr Wieslaw Krawcewicz, Professorat the University of Alberta and Dr KlausHoechsmann, Professor Emeritus at UBC.The PIMS Education prize committee, con-sisting of the six Site Directors, was unani-mous in choosing these two from a field ofseven nominees, that are all very deservingindividuals in their own right.Wieslaw Krawcewicz is the creator andmoving force behind the highly successfulnew magazine “Pi in the Sky,” which waslaunched two years ago under PIMS sponsor-ship.  This magazine, devoted to improvingawareness of mathematics among high schoolstudents, has been distributed free of chargeto all high schools in Alberta and British Co-lumbia, as well as selected sites throughoutNorth America.It has an attractive format, lots of jokes andcartoons, as well as articles written on math-ematical topics, often with an angle of rel-evance to teenage life.  For example, the firstissue had its lead article entitled “A Date withMath” and had five enthusiastic schoolgirlson the cover.  The magazine is also availableonline.As one of his colleagues commented, “Atthe beginning I was skeptical.  I did not be-lieve that such a project could be finalized.Wieslaw was extremely active in convincingand encouraging people, including myself, toPIMS  Awards Ceremony at SFU Harbour Centreparticipate.  He did all kinds of work fromediting and writing articles to making car-toons and math jokes.  He had long discus-sions with high school students, undergradu-ates, teachers and other people involved ineducation.  Wieslaw’s enthusiasm is conta-gious.”The director of curriculum and pro-grammes in the Edmonton public school sys-tem remarked “Our high school mathematicsdepartment heads all look forward to themagazine and frequently utilize its contentsto enrich the math programme for their stu-dents.  This publication has certainly helpedto increase interest in mathematics.  The con-tributions of Dr Krawcewicz to the studentsin Edmonton Public Schools have been andcontinue to be significant in helping to raisethe bar in mathematics education.  He is amost deserving candidate for the PIMS Edu-cation award.”One of Wieslaw’s colleagues noted that“the University of Alberta (and I expect otherPIMS universities as well) is seeing the posi-tive effect of Dr Krawcewicz’s efforts.  Sincethe introduction of the magazine, enrollmentin the first-year Honours Calculus classes atUA has approximately doubled; enrollmentin our second year class has actually tripled.The magazine has made many students awarethat mathematics can be interesting.”Sharing this year’s prize is another personwho has worked far beyond the call of dutyin math education and increasing publicawareness and appreciation of mathematics,Professor Klaus Hoechsmann. Even beforePIMS existed, he has been devoted to thecause of mathematics education.  At UBC hedeveloped, and was the first teacher of, thecourse “Mathematics by Inquiry” (Math 336),which has become the centrepiece of the newCertificate Programme for MathematicsTeachers, cosponsored by the Mathematicsdepartment and the Curriculum Studies de-partment of the Education Faculty.  It is acourse designed to provide hands-on math-ematical experience to educators.   One of hisformer students — now teaching mathemat-ics at a BC high school — remarked “Usingthe principles he teaches, ‘mathematics, likesinging, is for everyone — not only the threeDick Peter (Dean of Science, U of A) andEducation Prize Winner Wieslaw KrawcewiczKen Foxcroft (TD Securities), Research PrizeWinner Kai Behrend and Ron Graham (San Diego)Winter 2002 9Pacific Institute for the Mathematical Sciencesof this, the nominators argued that there wasreally no conflict in awarding the PIMS Edu-cation prize to one of our own employees.  In-deed the prize is richly deservedfor all the effort Klaus has de-voted over the years to math-ematical education and publicawareness.This year the committee, DrArvind Gupta (Chair, MITACS),Dr Shahid Hussein (Telus), Mr Randy Savoie(Ballard Powersystems), Mr Jack Fujino(Stantec), Dr Bryant Moodie (University ofAlberta), and Dr Chris Bose (University ofVictoria), received seven nominations for thePIMS Industrial Prize. They were impressedby the significant contributions made by allthe candidates. It is clear that industrial-uni-versity research programmes are thrivingacross the country.The committee felt that two nominationsstood out from the others. After considerabledebate, they chose to recommend that DrMichael Kouritzin (University of Alberta) andDr Martin Puterman (University of British Co-lumbia) share this year's industrial prize.The committee was very impressed that soearly in his career, Dr Kouritzin has estab-lished a strong and well known industrial re-search programme. He founded the PINTSCentre (Predictions in Interacting Systems)which is supported by MITACS and PIMS.The centre focuses on novel filtering theoryto track various types of objects from lostships to pollution. His industrial partnersunanimously agreed that Michael's researchis having a significant impact on their ownbusiness plans. It is difficult to imagine anyone who hasput more time and energy into establishingclose university-industry collaborations thanDr Puterman. Dr Puterman has a long and dis-tinguished research career, most recently win-ning the Lancaster Prize. He was also an earlyadvocate of industry-university research aspivotal to operations research. This lead to thecreation of the Centre for Operations Excel-lence (COE) at UBC. COE recieves signficantsupport from MITACS, PIMS, and a signficantnumber of partner companies. Dr Puterman'svision of giving students high level researchtraining in an industrial-university setting isa model that is a testament to what can beaccomplished through vision and hard work.The keynote address at the ceremony wasgiven by Dr Philippe Tondeur, Director of theDivision of Mathematical Sciences at the Na-tional Science Foundation and Professor ofMathematics at the University of Illinois inUrbana-Champaign.During his years at NSF Dr PhilippeTondeur has become an articulate voice forthe role of the Mathematical Sciences in theU.S. Science and Engineering enterprise. Itis worth noting that even after the tragic eventsof September 11th  the NSF has received an8.4% increase for Fiscal Year 2002.Closer to home, the birth of BIRS  will al-ways be connected to the leadership ofPhilippe Tondeur at the NSF. There is nodoubt that the world mathematical commu-nity owes BIRS to the clarity of vision and tothe far-sightedness of Philippe Tondeur.tenors.’ Klaus inspires teachers to love andunderstand mathematics.”Upon becoming Chair of the PIMS Edu-cation Committee, Klaus trulywent into high gear, putting tre-mendous enthusiasm into PIMS’educational and outreach pro-grammes.  He co-organized theinnovative “Changing the Cul-ture” conferences, a BC forumfor elementary, high school, and post-second-ary math educators.  Klaus was instrumentalin creating the PIMS Elementary SchoolMathematics Contest (ELMACON) in partner-ship with the BC Association of MathematicsTeachers.  He has spent countless hours withBCAMT people and individual teachers, madepresentations at schools and conferences, andcompletely revamped PIMS’ activities in K-12 education. Many contributions to “Pi inthe Sky” were authored by Klaus.To celebrate the year 2000, the Interna-tional Mathematics Year, Klaus designed andexecuted the hugely successful “Mathemat-ics is Everywhere” poster campaign.  Eachmonth of the year a new poster would appearon buses in the lower mainland, with an at-tractive graphic and a mathematical problem,offering a $100 prize for its solution, alongwith a web address for further information.The enthusiastic response of the public wasbeyond anyone’s expectations.  These post-ers also became the basis for the first PIMScalendar, which are now becoming collector’sitems.  A sequel to this poster campaign, cel-ebrating Women in Mathematics, was devel-oped by staff  in the PIMS office, with Klaus’encouragement.The most innovative and ambitious ofHoechsmann’s contributions, perhaps, is thefull-length play “Hypatia’s Street Theatre.”This is a dramatization based on the life ofan early woman mathematician and philoso-pher in Alexandria, and is unique in that itactually teaches mathematical concepts withinthe play.  It was performed in December 2000to a full house in the Frederic Wood theatreon the UBC campus.  Klaus not only wrotethe script (with the assistance of professionalplaywright Ted Galay), but worked with theprofessional actors and stage crew through-out the rehearsals.  He also paid for the pro-duction, devoting all of his (modest) stipendas a PIMS employee to the cause.

Toronto)Gideon Schechtman (Weismann Inst.)Gilles Pisier (U. of Paris VI and Texas A&M)Asymptotic Geometric Analysis is con-cerned with the geometric and linear proper-ties of finite-dimensional convex bodies, es-pecially with the asymptotics of various quan-titative parameters as the dimension of the un-derlying space tends to infinity. The tech-niques here combine geometric, analytic,probabilistic and combinatorial methods. Themain directions of study are:• Convex Geometric Analysis includingproblems from  Classical Convexity and Iso-morphic Geometry.• Asymtotic Combinatorics includingquestions in Complexity Theory and Compu-tational Geometry.• Certain aspects of Statistical Physicsthat deals with “Threshold” and “Phase Tran-sition” phenomena.The main probabilistic tools used are de-viation inequalities and the concept of con-centration of measure phenomenon, which infact is, an isomorphic form of isoperimetrictype inequalities.  Measure Transport meth-ods and related PDEs have provided new andpowerful Geometric Inequalities of Brunn-Minkowski and Brascamp-Lieb type as wellas novel approaches to Log-Sobolev andTalagrand-type inequalities.  The subject isalso connected with quantized functionalanalysis via important estimates for the dis-tribution of eigenvalues and norms of randommatrices, as well as with some aspects of freeand quantum information theories, operatorspaces and non-commutative Lp spaces.The goal of this thematic programme is tobring together some areas of Mathematics andComputer Science which are dealing with as-ymptotic behavior of different parameterswhen the dimension, or a number of otherrelevant free parameters, increases to infin-ity. The main directions of this subject ofstudy are Convex Geometric Analysis (As-ymptotic Theory of Convex Bodies andNormed Spaces), some problems of DiscreteMathematics (one may call it AsymptoticCombinatorics) including problems of Com-plexity Theory, and some problems of Statis-tical Physics.  Closely connected are alsosome directions in Probability and in PDEs,including non linear PDEs arising from prob-lems in Convex Analysis and Geometric In-equalities.  The main activity will concentratearound Convex Geometric Analysis, but un-derstood in a very broad sense, as the intentis to involve a large number of main peopleof other related fields.The intent is to bring together senior ex-perts and young researchers, postdocs andadvanced Ph.D. students, with an emphasison a major participation from the young gen-eration.ProgrammeConference on Convexity andAsymptotic Theory of Normed SpacesPIMS-UBC, July 1-5, 2002Organisers: Erwin Lutwak (Warsaw) andAlain Pajor (Marne-La-Vallée).Topics include classical convexity, Radontransform and Fourier methods in convexity,asymptotic theory of high dimensional con-vex bodies, geometric functional inequalitiesand probabilistic methods in convexity,isoperimetric-type inequalities.Concentration Period on MeasureTransportation and GeometricInequalitiesPIMS-UBC, July 8-12, 2002Organiser: Robert McCann (U. Toronto)This concentration period will focus ontransportation of measure methods and theirapplications, concentration of measure phe-nomenon, geometric functional inequalities(Brascamp-Lieb, Sobolev, entropy, Cramer-Crao, etc), “isomorphic” form of geometricinequalities and probabilistic methods.Workshop on Phenomena of LargeDimensionsPIMS-UBC, July 14-20, 2002Organisers:  Vitali  Milman (Tel Aviv),Michael Krivilevich,  Laszlo Lovasz(Microsoft Research) and  Leonid Pastur (U.Paris VII).Topics include different phenomena ob-served in complexity theory, asymptotic com-binatorics, asymptotic convexity, statisticalphysics and other theories of very high para-metric families (or large dimensional spaces).Focused Research Groups on RandomMethods and High Dimensional SystemsPIMS-UBC, July 21-August 5, 2002Organisers: Vitali Milman (Tel Aviv) andNicole Tomczak-Jaegermann (U. Alberta).Topics include the asymptotic behavior ofdifferent parameters when the dimension, ora number of other relevant free parameters,increases to infinity.  The main direction isthe study of the asymptotic theory of convexbodies and normed spaces as well as their ap-plications to combinatorics and phase transi-tion phenomena.Workshop on Non-commutativePhenomena and Random MatricesPIMS-UBC, August 6-9, 2002Organisers: Gilles Pisier (U. Paris VI andTexas A&M) and Stanislaw Szarek (U. ParisVI and Case Western Reserve).Topics include the distribution of eigen-values of random matrices, norms of such ma-trices, some aspects of free and quantum in-formation theories, applications in manyfields, quantized functional analysis and op-erator spaces and non-commutative Lp  spaces.Workshop on Banach SpacesPIMS-UBC, August 12-15, 2002Organisers: Bill Johnson (Texas A&M andTed Odell (U. Texas, Austin).This workshop will focus on the asymp-totic theory of Banach spaces and other ap-plications of local theory to the geometry ofinfinite dimensional Banach spaces.Winter 2002 11Pacific Institute for the Mathematical SciencesThematic Programme B:Selected Topics in Mathematicaland Industrial StatisticsProgramme Organizers:Richard Lockhart (SFU)Charmaine Dean (SFU)Peter Guttorp (U. Washington)Chris Field (Dalhousie)R.H. Zamar (UBC)Randy Sitter (SFU)Agnes Herzberg (Queen’s)Michael Kouritzin (U. Alberta)Statistical models became, in the late 20thcentury, extremely complex and high dimen-sional.  One goal of this programme is to iden-tify opportunities and challenges for modeldevelopment and criticism and to begin tooutline approaches to assessment of complexmodels. This requires bringing together lead-ing practitioners and philosophers of scien-tific, Bayesian and frequentist modelling sta-tistics with leading researchers in model as-sessment, validation and goodness-of-fit.Robust Statistics and Statistical Comput-ing deal with methods designed for process-ing large  data sets of uneven quality (data-bases containing outliers, gross errors, miss-ing data, etc.).  One focus is on the efficientcomputation of robust estimates using verylarge data sets.Design and Analysis of Experiments areat the heart of the statistical sciences. Yet -unlike the designs originating from agricul-tural problems developed by Sir RonaldFisher in the 1920’s—many industrial prob-lems are not well-explored in the statisticalliterature. To help North American industrycompete globally, advanced statistical meth-ods suitable for real applications need to befurther developed.ProgrammeWorkshop on the Role of StatisticalModelling in the 21st CenturyPIMS-SFU, May 4-6, 2002Organisers: Richard Lockhart, CharmaineDean (SFU), and Peter Guttorp (UW).Statistical models have become more andmore complex. This workshop will bring to-gether leading practitioners and philosophersof scientific, Bayesian and frequentist mod-obliged to run their experimental points insequence and are thus able to plan their fol-low-up experiments guided by previous re-sults, unlike agriculture, in which all resultsare often harvested at one time, and (iii) mod-els can be very complicated in industrial andscientific experimentation, sometimes theyare nonlinear, and computer modelling andfinite element analysis is required.PIMS-MITACS Workshop onFiltering Theory and ApplicationsU of A, July 20-26, 2002Organisers: Robert Elliott (U. of Calgary),Michael Kouritzin (U. of Alberta), Tom Kurtz(U. of Wisconsin at Madison), Hongwei Long(U. of Alberta)Filtering theory is an active and current re-search field attracting many applied probabi-lists. In particular, there is increasing interestin applying filtering theory to real-worldproblems in areas such as mathematical fi-nance, target detection and tracking, commu-nication networks, pollution tracking, weatherprediction, traffic management, and searchand rescue.  We believe that the proposedmeeting will help to advance scientific devel-opment of filtering theory and its applicationsand offer benefits to industry. In particular,this meeting will encourage local researchactivity in this field and identify additionalindustrially-motivated filtering problems.The meeting is planned to precede the2002 IMS Probability Symposium in Banff.elling statistics with leading researchers inmodel assessment, validation and goodness-of-fit.  The goals are to identify opportunitiesand challenges for model development andcriticism and to begin to outline approachesto assessment of complex models.International Conference on RobustStatistics (ICORS 2002)UBC, May 12-18, 2002Organisers:  Luisa Fernholz (Temple Univ.),Ursula Gather (Dortmund), Chris Field(Dalhousie) and R. H. Zamar (UBC).This conference will be a forum for newdevelopments and applications of robust sta-tistics and statistical computing.  Experiencedresearchers and practitioners, as well asyounger researchers, will come together toexchange knowledge and to build scientificcontacts.The conference will centre on methods de-signed for processing large datasets of unevenquality (databases containing outliers, grosserrors, missing data, etc.). This conference ex-pects to touch upon many different aspectsof data analysis in a fashion which integratestheoretical and applied statistics. One focuswill be on the efficient computation of robustestimates using very large data sets.Design and Analysis of Experiments,Coast Plaza Suites HotelVancouver, July 14-18, 2002Organisers: Randy Sitter (SFU), DerekBingham (Michigan),  Bruce Ankenman(Northwestern) and Agnes Herzberg(Queen’s).Many industrial problems are not well-ex-plored in the statistical literature. To helpNorth American industry compete globally,advanced statistical methods suitable for realapplications need to be further developed.Statistical experimental designs, developed bySir Ronald Fisher in the 1920’s, largely origi-nated from agricultural problems. Althoughthe design of experiments for industrial andscientific problems may have the same basicconcerns as design for agricultural problems,there are many differences: (i) industrial prob-lems tend to require investigation of a muchlarger number of factors  and usually involvea  much smaller total number of runs (obser-vations), (ii) industrial results are more repro-ducible, (iii)  industrial experimenters areWieslaw KrawcewiczVol. 6, Issue 112 Pacific Institute for the Mathematical SciencesNew Members to the Scientific Review Panel of PIMSContinuing members of thePIMS Scientific Review Panel• Dr Nassif Ghoussoub, Director, PIMS• Dr David Brillinger, Professor of Statis-tics, University of California, Berkeley• Dr Robert V.

The form of an object is that character-istic which remains invariant under a groupof transformations consisting of translation,rotation and possibly reflection.  He showedthat many commonly used methods base in-ference on non-identifiable parameters and hediscussed the scientific implications of thosemethods.  Throughout the presentation, herelated the theoretical concepts to his projectson the shapes of skulls of children withDown’s syndrome which motivated his theo-retical work.Jenny Bryan’s illuminating seminar was en-titled “Finding Informative Genes based onMicroarrays and Deletion Sets”.  Her work fo-cuses on modelling gene expression data whereit is informative to find sets of genes that ex-hibit interesting expression profiles or groupsof genes that appear to be functionally related.In her talk, she discussed the research questionsposed for such data and the challenges and op-portunities they present for statisticians.by Mary Lesperance, University of VictoriaVol. 6, Issue 114 Pacific Institute for the Mathematical SciencesThis Congress built on the success of thefirst one held at Tsinghua University,Beijing, in August 1999, and was aimed atdeveloping further the collaborative re-search effort between the two countries.

As an applied mathematician, oneneeds a firm grasp of the experimental data, and facility in math-ematical modeling and analysis. Simulation plays an especiallyimportant role in their mathematical study and the beautiful dy-namics seen in Figure 1 lies beyond our current abilities.Mathematically, we approach FBPs by considering a time-dependent domain Ω(t), with boundary Γ(t), which contains afluid. Our goal is to determine the motion of Ω(t) and thus ofΓ(t). For “regular” fluids, like water and glycerin, the evolution inspace and time of the fluid’s velocity u(x, t) is described well bythe Navier-Stokes (N-S) equations, which is a version of Newton’ssecond law for a continuously deformable media:ρ[∂u∂t+ u · ∇u]= −∇p + µ∆u (1)Here p(x, t) is fluid pressure, ρ the fluid density, and µ the shearviscosity. We are usually interested in incompressible fluids, andso Eq. (1) is supplemented by the condition ∇·u = 0, which is anexpression of conservation of mass. This is a global constraint onthe system and means that the dynamics has an elliptic bound-ary value problem at its core. In free boundary problems, theincompressibility constraint is a strongly complicating factor inhow these problems are treated both analytically and numerically.To finish the mathematical description we need boundary con-ditions at Γ(t), which we now imagine separates two fluid domainsΩ1(t) and Ω2(t). One boundary conditions says that Γ(t) movesat the velocity of the fluids on either sides, which are equal, orvelocity of Γ = u1|Γ= u2|ΓThe next condition is more complicated. Fluid boundaries willtypically exert a force, or stress, on the surrounding fluids. Rewritethe RHS of the N-S equations as−∇p + µ∆u = ∇ · Π (2)The matrix Π is called the stress tensor, and describes the internalstresses of the fluid. The second boundary condition is that thejump in fluid stress across the boundary is given by the stress Sexerted by the boundary on the fluid, or[Π|Γ] · nˆ = S.This closes the system but for the prescription of S, where morevery interesting physics can enter the problem. If the two fluidsare immiscible, then there is surface tension and S is taken as pro-portional to the mean curvature of the boundary. If the boundaryis a mechanical object, like the material of a flag, then S mustcapture the inertial, and other, forces of that surface.The second lecture discusses numerical methods that are usedto circumvent some of the special difficulties that arise with sur-face stresses such as surface tension, or elasticity, which dependon the geometry of the boundary. Such stresses bring high spatialderivatives, both nonlinearly and nonlocally, into the dynamics,Figure 1: Fluid hits a flat plate, and is expelled sideways. From "Fluid polygons", by R. Buckingham and J. Bush, Physics ofFluids 13, S10 (2001).This article is an overview, based on his first introductory lec-ture, of the five lectures given by Michael Shelley at PIMS–SFU inNovember and December of 2001.What is a free boundary problem (FBP) in fluid dynamics?Figure 1 shows one. This is an experiment performed by JohnBush and Buckingham of MIT. A fluid flowing from a pipe hits aflat plate, and is expelled sideways as an expanding sheet. Thissheet breaks up into jets of liquid that themselves continue tocollide and split to form a linked pattern. In this flow both theinertia and viscosity of the fluid are important physical factors, asis the surface tension of the very dynamic boundary of the liquid.And so, a free boundary problem occurs when the dynamics ofa fluid system involves determining also the dynamics of a bound-ary. This boundary could be that which actually bounds the fluid,as in Figure 1, or it could be a boundary that separates two dif-ferent fluids, or even a boundary within a single fluid. FBPs arevery common and central in fluid dynamics, often visually arrest-Figure 7:Numerical determinationof fluid flow, wake, andbody deformation usingan elastic surface.Vol. 6, Issue 122 Pacific Institute for the Mathematical SciencesFigure 3:An experiment showing thenonlinear development ofSaffman-Taylor instability ina non-Newtonian liquid.Courtesy of Peter Palffy-Muhoray and Roland Ennis(Liquid Crystal Institute, KentState University).making naive implementations of the dynamics very stiff. In Hou,Lowengrub and Shelley [1,2] is developed the “Small-Scale De-composition”, which is a basis for numerical methods that removethese difficulties, and have become a standard method for this classof problems (see Hou, Lowengrub, & Shelley [3]). These methodshave lead to the discovery of unexpected phenomena. A classi-cal free-boundary problem that captures the mixing of two fluidsshearing past one another arises from the Kelvin-Helmholtz insta-bility. Figure 2 shows the result of applying the SSD to study thedevelopment of the KH instability when the two fluids are immis-cible, and the interface between them is under a surface tension.The interface began nearly flat, and has “rolled-up” into intricatespirals. Further, we found that the interface generically collidedwith itself – as is nearly the case in the figure – yielding finite-time“topological singularities” that are presumably the precursors tothe formation of separated fluid droplets.FBPs are also closely associated with problems in pattern for-mation in soft condensed matter, which is the subject of the thirdlecture. The fluid archetype arises from Hele-Shaw cells, whichis the simple experimental setup of two glass plates separated bya small gap. After filling this gap with a fluid, say glycerine, airis pumped in through a small hole to form an expanding bubblethat displaces the liquid. This bubble is unstable to the Saffman-Taylor instability, which is mediated by surface tension, and yieldsdensely branched patterns which have been much studied and sim-ulated (see [1,3]). There are related fundamental instabilities insolidification processes, and, in biology, similar patterns emerge inthe growth of bacterial colonies.However, other interesting things also happen when the cell isfilled with more exotic liquids, like liquid crystalline fluids or poly-meric liquids. These fluids are “non-Newtonian” and can store andrelease stress, or have flow dependent viscosities, among other nov-elties. (The stress tensor is no longer that found in Eq. (2), but ismore complicated, and often unknown.) While these fluids behaveFigure 5: A suspended silkenthread flapping in a runningsoap-film.Figure 6: A nylon fiber beingdeformed by the oncoming flowof a running soap-film.strangely, they are also part of our modern life, making their wayinto computer displays and shampoos. Modeling of these systemsbecomes central, the resulting mathematical descriptions more in-volved, and the simulations even more difficult [4,5]. Figure 3shows an experiment by Peter Palffy-Muhoray and Roland Ennisat the Liquid Crystal Institute (Kent State) when the outer fluidis “shear-thinning”, a common property of nematic and polymericliquids. Plainly the pattern is structured around a few stable fin-gers, and looks much like a snowflake. Figure 4 shows a numericalsimulation using a shear-thinning version of “Darcy’s Law”, whichgoverns Hele-Shaw flows. These simulations reveal that the emerg-ing fingers are associated with strongly reduced viscosities at theirtips.A very different kind of free boundary problem involves “iner-tial boundaries”. Inertial boundaries include heavy surfaces whichinteract with the fluid, like flags and fish. In these cases the in-ertia of the object is an important factor in the resulting fluidinteraction. For these problems the surface stress, S, is now afunction of the acceleration of the interface (inertial forces), andother internal stresses of the mechanical object; Surface stress nowreflects much more than just geometry. Figure 5 shows the resultof immersing such an inertial object in a strongly flowing fluid. Inthis experiment, performed at the Courant Institute Applied MathLab, a silk thread is suspended into a flowing soap-film. This isan experimental analog of a 1-D flag in a 2-D flow. When thethread is long enough, so that its mass comes into balance withthe mass of the fluid with which it interacts, it begins to flap likea flag. The interaction of fluids with such boundaries is an area ofcurrent and active research, both in formulation and simulationalmethods (see Zhu & Peskin [7] for some first simulations in thisdirection).In the final lecture is discussed very recent work concerningbody flexibility and fluid drag. The motivation for this is the ob-servation that in a strong wind, a flexible leaf will change its shape,Figure 2: Applying the SSD to the study of the Kelvin-Helmholtz Instability.Winter 2002 23Pacific Institute for the Mathematical SciencesReferences:[1] Removing the Stiffness from Interfacial Flows with Surface Ten-sion, by T.

To study this effect experimen-tally a flexible plate is placed in a flowing soap-film, and its drag ismeasured as the flow velocity U increases and the “body” becomesmore streamlined. (Figure 6, courtesy of Alben, Xia, Zhang, andShelley, in preparation). The experimental finding is that ratherthan growing like U2, as is expected and found for a rigid body,the drag grows like Uα for some α < 2. Shelley and his collab-orators have constructed mathematical models, and solved themnumerically, that simulataneously solve for the flow, the body de-formation, and the wake. A numerical solution of this flow modelis seen in Figure 7. Analysis of this mathematical model revealsa transition in drag behavior at a critical non-dimensional flowvelocity: Below the transition, drag scales as U2, and above thetransition as U4/3.Figure 8: Hanging oscillating chain.Figure 8 shows a comparison of experiment and theory for the nonlinearpatterns that form when a hanging chain is oscillated at its support point.This is the most classical, indeed the grand-daddy, of "inertial free bound-ary problems".

Posters were distributed toschools in BC, Alberta and Washington State,as well as to departments and individualsthroughout North America who had requestedto be added to the mailing list, and to librar-ies in the Vancouver area.  As withthe "Mathematics is Everywhere"campaign of 2000, a wall calendarfeaturing the full set of pictures andquotes was published.   This calen-dar was designed by Heather Jenkinsand Krisztina Vasarhelyi.In September we featured EmmyNoether arguably greatest womanmathematician ever.  Her talent forabstraction was unique and she waslegendary for her ability to inspirestudents and stimulate creative andproductive research. One of her stu-dents, van der Waerden, writes: "For EmmyNoether, relationships among numbers, func-tions, and operations became transparent,amenable to generalisation, and productiveonly after they have been dissociated from anyparticular objects and have been reduced togeneral conceptual relationships."Russian Sofia Kovalevskaya, best knownfor her work on partial differential equations,was the subject of the October contest.  Shestudied under Karl Weierstrass and theCauchy-Kovalevskaya Theorem bears hername.  Her introduction to mathematics wasthrough the wallpaper in her room whichcame from the pages of an old calculus text!She was inspired by the mysterious sym-bols and resolved to find out more aboutthem.In November observational astronomerCaroline Herschel appeared.  Her brother,the famous astronomer William Herschel, res-cued her from a dreary fate of householdchores and encouraged her to study, and shedid so with great enthusiasm.  Caroline's firstmajor scientific breakthrough was the dis-covery of a comet, and her first experiencein mathematics involved the calculation ofthe positions of nebulae.  She also cataloguedevery discovery that she and William hadmade.Maria Gaetana Agnesi, a child prodigy,gifted in mathematics and languages whoseonly dream was to help others, was featuredin December.   Maria's most famous publica-tion was a teaching text that helped make cal-culus accessible to people other than profes-sional mathematicians. Her "academic career"ended relatively early in her long life whenshe abandoned mathematics and devoted her-self solely to charitable deeds.The final month of the contest fea-tured Emilie de Breteuil, a genius, wholived a fast and reckless life in Parissociety.  She had a passionate interestin Newton's work and her translationof Newton's "Principia", for manyyears the only French translation,helped to shape the direction for sub-sequent work in mathematics inFrance.The recent winners of the contest will fea-ture in an upcoming issue of the PIMS news-letter.

In 5 shortyears, PIMS’ scientists have collectively con-ceived of, and built an entity that has galva-nized the mathematical community. The in-stitute is now recognized world-wide as aneffective new model for the mathematical sci-ences: one that addresses simultaneously theimperatives of research, education and tech-nology transfer, and one that was able to unitea diverse community of many institutions overa geographically challenging area.PIMS’ early successes re-invigorated theCanadian mathematical science communityand stimulated its institutions. The institute’sproactive approach to industrial and educa-tion outreach, and its use of modern commu-nication and dissemination tools, contributedto changing the culture, to erasing outdatedperceptions and to increasing mathematicalawareness. PIMS’ energetic and vocal effortson behalf of the mathematical sciences led toa re-affirmation of their key importance,whether in K-12 school programmes, or forleading edge Canadian R & D efforts.Through a series of bold national and in-ternational initiatives (the MITACS network,the Banff International Research Station,the Pacific Northwest Partnership and thePacific Rim Initiative), PIMS has raised theprofile of Canadian research throughout theworld. By developing key partnerships, PIMSmultiplied the opportunities and attracted sub-stantial investments from industrial, provin-cial, federal and foreign sources in supportof Canadian-led research.Dr Tom Brzustowski, President NSERC:“The hallmark of a good idea is that so manypeople find it obvious once it has beenmentioned - obviously!" Dr Rita Colwell, Director of NSF:"BIRS underscores how international coopera-tion adds up to more than what any nation couldaccomplish alone.”Dr Brzustowski’s and Dr Colwell’s speeches are on page 4-5.Banff  Station LaunchedOn September 24, 2001, the governments ofAlberta, Canada and the United States an-nounced the establishment of a new interna-tional mathematical research facility in Banff,Alberta. The Banff  International ResearchStation for Mathematical Innovation andDiscovery (BIRS) will annually host  thou- please see “Banff Station” on page 25sands of top international scientists and re-searchers for intense workshops, collabora-tive research efforts, and training sessionsacross the entire spectrum of pure and ap-plied mathematical sciences.
