Title: Deformation quantization of coadjoint orbits
Abstract:
Kirillov's famous orbit method suggests that irreducible unitary representations of a Lie group could be obtained by quantizing its coadjoint orbits via geometric quantization. The case of noncompact semisimple groups has remained unsettled due to lack of invariant polarizations on the orbits. Inspired by the work of Gukov and Witten, we propose a new way to quantize coadjoint orbits using hyperkahler structures and deformation quantization. Part of the project is joint work in progress with Conan Leung.
