Title:
Blocks and Defect Groups of SLn

Speaker:
Nate Harman

Abstract:
The modular representation theory of a finite group naturally breaks into different pieces called blocks, and the defect of a block is a sort of measure of its complexity. I will recall some basic aspects of this theory, and then give the complete classification of blocks and their defect groups for SLn(𝔽q)SLn(Fq) in defining characteristic.
