*讲座内容简介：

The coadjoint orbit method of Kirillov and Kostant suggests that irreducible unitary representations of a Lie group can be constructed as quantization of coadjoint orbits of the group, which was later reformulated by Vogan in algebro-geometric language for noncompact reductive Lie groups. I will propose an approach to this conjecture using deformation quantization and W-algebras. This is based on joint work with Conan Leung and ongoing project with Ivan Losev.
