To prove this we study the rationality of the actions of automorphisms on the graded quotients of the weight filtration of the $l$-adic cohomology groups."""@en ; edm:aggregatedCHO "https://circle.library.ubc.ca/rest/handle/2429/63002?expand=metadata"@en ; dcterms:extent "32 minutes"@en ; dc:format "video/mp4"@en ; skos:note ""@en, "Author affiliation: University of Tokyo"@en ; edm:isShownAt "10.14288/1.0355528"@en ; dcterms:language "eng"@en ; ns0:peerReviewStatus "Unreviewed"@en ; edm:provider "Vancouver : University of British Columbia Library"@en ; dcterms:publisher "Banff International Research Station for Mathematical Innovation and Discovery"@en ; dcterms:rights "Attribution-NonCommercial-NoDerivatives 4.0 International"@en ; ns0:rightsURI "http://creativecommons.org/licenses/by-nc-nd/4.0/"@en ; ns0:scholarLevel "Postdoctoral"@en ; dcterms:isPartOf "BIRS Workshop Lecture Videos (Banff, Alta)"@en ; dcterms:subject "Mathematics"@en, "Algebraic geometry"@en, "Number theory"@en ; dcterms:title "Degeneration of K3 surfaces and automorphisms"@en ; dcterms:type "Moving Image"@en ; ns0:identifierURI "http://hdl.handle.net/2429/63002"@en .
