We discuss restrictions of irreducible representations to reductive subgroups with focus on geometric question:[ abstract (pdf) ]
If time permits, we shall also discuss the following related questions for orthogonal groups of rank one.
- Classification of confomally covariant symmetry breaking operators on differential forms.
- Period of irreducible unitary representations.
- Occurrence of complementary series representations in branching laws.
