Algebraic Geometry Seminar - Rachel Webb
Title: The Abelian-Nonabelian Correspondence for Quasimap I-functions
Speakers: Rachel Webb (University of Michigan)
Abstract: When a complex reductive group G with maximal torus T acts on an affine variety S, one can form two (GIT) quotients: W//G and W//T. With the right hypotheses, W//G and W//T are both smooth projective varieties. The relationship between the cohomology rings of these two varieties is well understood. I will discuss the relationship of their quantum cohomology using the quasimap theory of Ciocan-Fontanine and Kim. In particular, I will present the abelian-nonabelian correspondence for quasimap I-functions when W is a vector space and G is connected.
