Title:
Minimal tilting complexes and generic direct summands of tensor products for reductive algebraic groups
Abstract:
Let G be a reductive algebraic group over an algebraically closed field of positive characteristic. In this talk, I will explain a new approach to studying tensor products in the category of rational representations of G, via minimal complexes of tilting modules. I will also explain how this approach allows us to define a new class of indecomposable G-modules, called "generic direct summands", which appear generically in Krull-Schmidt decompositions of tensor products of simple G-modules.
