## *Symmetry Breaking Operators: General Theory and Concrete
Construction for Reductive Groups* (opening lecture/2 lectures).
Representation Theory of Lie Groups, Mathematical
Physics, and Dynamical Systems. Université de Reims, France, 24-29
June 2019.

The lectures highlight infinite-dimensional representations of real
reductive groups with focus on induction and restriction. I begin with the general
results such as geometric criterion for finiteness (of uniform
boundedness) of the multiplicities of irreducible representations
occurring in induction and restriction.
Symmetry breaking operators are morphisms that describe restriction of
representations.
In the second lecture, I plan to discuss construction problem of ''symmetry breaking operators in a concrete geometric setting.
