Geometry and Representations of Reductive
Groups
Thursday, December 13

Abstract: The Kirillov-Kostant "orbit
philosophy" says that unitary irreducible representations of Lie groups should
correspond
(by "quantization") to symplectic homogeneous spaces. Symplectic homogeneous
spaces are very easy to understand, but "quantization"
remains mysterious. I'll talk about some of the things that we do understand,
and about ways to approach the problems that remain.
The most important geometry that appears is the geometry of conjugacy classes
of nilpotent matrices.
