17 Aug 1994 | | Journal: | Commun.Math.Phys. 174 (1995) 561-604 | | Abstract: | This paper further develops the combinatorial approach to quantization of the Hamiltonian Chern Simons theory advertised in cite{AGS}. Using the theory of quantum Wilson lines, we show how the Verlinde algebra appears within the context of quantum group gauge theory. This allows to discuss flatness of quantum connections so that we can give a mathe- matically rigorous definition of the algebra of observables $A_{CS}$ of the Chern Simons model. It is a *-algebra of ``functions on the quantum moduli space of flat connections’’ and comes equipped with a positive functional $omega$ (``integration’’). We prove that this data does not depend on the particular choices which have been made in the construction. Following ideas of Fock and Rosly cite{FoRo}, the algebra $A_{CS}$ provides a deformation quantization of the algebra of functions on the moduli space along the natural Poisson bracket induced by the Chern Simons action. We evaluate a volume of the quantized moduli space and prove that it coincides with the Verlinde number. This answer is also interpreted as a partition partition function of the lattice Yang-Mills theory corresponding to a quantum gauge group. | | Source: | arXiv, hep-th/9408097 | | Services: | Forum | Review | PDF | Favorites | |
