Broué’s Abelian Defect Group Conjecture II

Presenter
September 16, 2020
Abstract
In this second talk about Broué’s Abelian Defect Group Conjecture, we will explain its geometric version in the case of finite groups of Lie type: the equivalence should be induced by the cohomology complex of Deligne-Lusztig varieties. This was actually the main motivation for the conjecture in the first place. We will illustrate those ideas with the case of $SL(2,q)$.
