Title: Toric Stacks and Applications to Cycle Theory
Abstract: No prior knowledge of stacks will be assumed for this talk. We will discuss the theory of toric stacks, which like toric varieties, is a class of stacks which is particularly amenable to computation. Using the theory developed, we will show that it is impossible to construct a degree map for 0-cycles on even the nicest of Artin stacks. We will discuss our result within the broader context of Grothendieck-Riemann-Roch for stacks. This is based on joint work with Dan Edidin and Anton Geraschenko.
