Title: Branching laws for discretely decomposable restrictions
Date (JST): Thu, Aug 15, 2013, 15:30 - 17:00
Place: Seminar Room A
Abstract: Branching law tells how a given representation of a group decomposes when restricted to a subgroup. For non-compact real reductive groups, branching laws are very complicated and far from being understood in general. However, there are nice classes for the detailed study of branching laws introduced by Kobayashi as "discretely decomposable restrictions". In this talk, we discuss the discrete decomposability of restrictions and give explicit branching laws in this framework by using D-modules on the flag variety.
