Quantum conjugacy classes of simple matrix groups
arXiv:math/0412538
Abstract
Let be a simple complex classical group and $\g$ its Lie algebra. Let $\U_\hbar(\g)$ be the Drinfeld-Jimbo quantization of the universal enveloping algebra $\U(\g)$. We construct an explicit $\U_\hbar(\g)$-equivariant quantization of conjugacy classes of with Levi subgroups as the stabilizers.
