Abstract
A classical problem in representation theory is to understand how an irreducible representation of a group decomposes when restricted to its subgroups. Such questions are commonly referred to as branching problems.
In this talk, we will explore the restriction of all irreducible smooth representations of the quasi-split unramified unitary group U(1,1) to its hyperspecial maximal compact subgroup K. We will present explicit branching rules in this setting and discuss several applications that arise from having a concrete description of these restrictions
