Restriction of Unitary Representations of Real Reductive Groups.
Number Theory Seminar. Harvard University, 28 May 2008.

Branching problems ask how an irreducible representation of a group decomposes when restricted to its subgroup. Having an observation of bad features of branching problems in a general non-compact setting even for real reductive symmetric pairs, I will discuss how to find a nice setting for branching problems, and give an upper estimate on multiplicities. If time allows, some applications are also presented.
