Title: Periods and distinction problems
Abstract: Let G be a topological group and H a closed subgroup of G. An irreducible representation of G is said to be H-distinguished if it admits a linear form that is H-invariant. Given a pair (G,H) it is a natural question to classify all irreducible H-distinguished representations of G. I will begin the talk by describing why such distinction questions are interesting in representation theory. After that we will see some recent classification results for certain specific "symmetric" pairs (G,H).
