Dirac operators on quasi-Hamiltonian G-spaces

Abstract

We develop notions of twisted spinor bundle and twisted pre-quantum bundle on quasi-Hamiltonian G-spaces. The main result of this paper is that we construct a Dirac operator with index given by positive energy representation of loop group. This generalizes the quantization of Hamiltonian GG-spaces to quasi-Hamiltonian G-spaces.
