Title: Ext Analogues of Branching Laws
Speaker: Dipendra Prasad, TIFR Mumbai
Abstract: The decomposition of a representation of a group when restricted to a subgroup is an important problem well-studied for finite and compact Lie groups, and continues to be of much contemporary interest in the context of real and p-adic groups. We will survey some of the questions that have recently been considered, and look at a variation of these questions involving concepts in homological algebra which gives rise to interesting newer questions.
