Title: Igusa stacks and exotic Hecke correspondences I
Abstract: In this talk I will discuss the conjecture of Liang Xiao and Xinwen Zhu on the existence of exotic Hecke correspondences between the special fibers of different Shimura varieties, and a generalization of their conjecture. I will then discuss my joint work in progress with Jack Sempliner on this generalized conjecture. I will also explain how to reinterpret exotic Hecke correspondences in terms of Igusa stacks.
