Branching problems for unitary representations

July 25 to July 29, 2011
at the

American Institute of Mathematics,
Palo Alto, California

organized by

Toshiyuki Kobayashi,
Bent Orsted,
and Birgit Speh

## Original Announcement

This workshop will focus on branching laws for the restriction of a unitary representation to a subgroup.
The central problem of the workshop
will be to find explicit branching laws. If the representations are discretely decomposable, then the
explicit branching laws are often of a combinatorial nature. Here
techniques from algebraic combinatorics will be extremely
important and many interesting combinatorial problems
should arise.

Another goal is elucidate the connection between the real and the *p*-adic situation.
and to analyze how different methods in the real and
*p*-adic case might lead to (conjecturally) similar phenomena. This
pertains in particular to the branching laws with discrete
spectrum.
