Title: Sheaves of modules on atomic sites and discrete representations of topological groups

Speaker: 李利平教授(湖南师范大学)

Abstract

A fundamental theorem of Artin asserts that the category of discrete representations of a topological group is equivalent to the category of sheaves over a certain orbit category equipped with the atomic Grothendieck topology. In this talk, we characterize sheaves, sheafification, and sheaf cohomology on atomic sites in terms of notions in representation theory of categories, and classify irreducible discrete representations of certain important topological groups, including the infinite symmetric group and the infinite general linear group over a finite field. This is a joint work with Di, Liang and Xu.
