Branching problems for unitary representations
July 25 to July 29, 2011
American Institute of Mathematics,
San Jose, California
and Birgit Speh
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
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
