Quantum Teichmuller theory and conformal field theory

Julien Roger (Rutgers)

Abstract: The aim of this talk is to investigate the possible connection between the quantum Teichmuller space and a certain type of conformal field theory. I will first introduce the notion of a modular functor arising from conformal field theory, and its applications to low dimensional topology. Then I will describe the construction of the quantum Teichmuller space, emphasizing the relationship with hyperbolic geometry. Finally, I will describe a possible connection between the two constructions, focusing on the notion of factorization rule. The key ingredients here are the Deligne-Mumford compactification of the moduli space and its Weil-Petersson geometry. I will introduce these notions as well.
