Description
Kostant's branching law for a symmetric pair $(\mathfrak{g},\mathfrak{k})$ determines the multiplicity of a irreducible $\mathfrak{k}$-module inside irreducible $\mathfrak{g}$-modules. In this talk I will explain how to derive this branching law using the language of Watanabe's integrable modules for quantum symmetric pairs. This is joint work in progress with Stefan Kolb.
