K-Theory and Motivic Homotopy Theory Seminar -- Ivan Kobyzev
Title: G-theory of root stacks and its application to equivariant K-theory. Speaker: Ivan Kobyzev, University of Western Ontario Abstract: There is a result from the 1980's that allows us to describe the equivariant K theory of curves: if X and Y are curves, G is a finite reducible group and Y = X/G, then we can write K_G(X) in terms of K(Y) and some representation rings associated to the group. We have generalized this result to any dimension using the description of the category of coherent sheaves on a root stack given by Borne and Vistoli. This is a joint work with A. Dhillon.
