Abstract: The coadjoint orbit method/philosophy suggests that irreducible unitary representations of a Lie group can be constructed as quantization of coadjoint orbits of the group. In this talk, I will propose a geometric way to understand orbit method using deformation quantization, in the case of noncompact real reductive Lie groups. This approach combines recent results on quantization of symplectic singularities and Lagrangian subvarieties. This talk is based on joint work with Conan Leung and ongoing joint project with Ivan Losev.
