Title: Classical Branching Laws

Abstract: We consider the classical branching laws; for example, that of understanding the decomposition of the highest weight representation of GL(n) to that of GL(n-1), or restriction from odd orthogonal to even orthogonal and symplectic branching laws. We outline an approach via the Weyl character formula. This is joint work with Sagar Srivastava.
