abstract: We analyze the hamiltonian quantization of Chern-Simons theory coupled to dynamical sources for any semisimple group. We introduce different Poisson algebras associated to this problem and proceed to the quantization of these structures and to the analysis of representation theory of some of these algebras.In particular we analyze in detail the quantization of particles coupled to SL(2,C) Chern-Simons theory following the classical analysis of Buffenoir-Noui. This is a joint work with E.Buffenoir.
