Title: Reductive Pairs from Representations of $$SL_2$$

Abstract:

Reductive pairs are a class of nice embeddings of algebraic groups. They have been used to salvage some good behaviour observed in characteristic 0 in the positive characteristic case, and also in providing uniform proofs of otherwise technical results. I will talk about research into deciding when we get reductive pairs arising from representations of an algebraic group, focusing on the groups $$SL_2$$.
