Yorck Sommerhäuser

Quantum groups and conformal field theory

Winter semester 2000/2001
Time: Tue 2:00 pm
Room: 251
Planning session: Thursday, October 18, 3:15 pm, Room 251
Contents: The aim of the seminar is to explain the connections between the theory of quantum groups, modular categories, and conformal field theory. We want to show how deformed enveloping algebras of semisimple Lie algebras as well as the Wess-Zumino-Witten model from conformal field theory lead to the notion of a modular category and a modular functor. The general principles will be explained by simple examples.
The seminar is based on the books of B. Bakalov und A. Kirillov on the one hand and the book of V. G. Turaev on the other hand. A good command of mathematics is required for participation.
