If you have a question about this talk, please contact Stacey Law.

The standard construction of the representation theory of S_n is based upon the combinatorics of Young Tableaux. In this talk I will explore a potential alternative construction: a ‘homological induction’ using sheaves of modules on Tits buildings. These methods were developed by Ronan and Smith in the 1980’s. Time permitting, I will also talk a little about the 2-category of complexes of groups and how it may relate to this problem.

This talk is part of the Junior Algebra and Number Theory seminar series.
