Algebraic Geometry Seminar - Wilberd van der Kallen
Title: Cohomological finite generation and bifunctorsSpeaker: Wilberd van der Kallen (University of Utrecht)Abstract: Let k be a field. Let G be a reductive algebraic k-group acting algebraically on a finitely generated k-algebra A. Then the cohomological finite generation property (CFG) holds: the cohomology algebra H^*(G,A) is a finitely generated k-algebra. This result fits into a long story, going from the First Fundamental Theorem of invariant theory to strict polynomial bifunctors and their cohomology. We will sample this story. The slides can be found at http://www.staff.science.uu.nl/~kalle101/Ohio2015 [pdf]Seminar URL: https://research.math.osu.edu/agseminar/
