Title: Positive Representations of Split Real Quantum Groups
Date (JST): Fri, Sep 21, 2012, 15:30 - 17:00
Place: Seminar Room A
Abstract: In this talk, I will introduce the family of positive principal series representations for split real quantum groups by positive self-adjoint operators. The construction of these representations gives the starting point of a new research program devoted to the representation theory of split real quantum groups initiated in the joint work with Igor Frenkel. It is a generalization of the special class of representations considered by J. Teschner for Uq(sl(2,R)) in Liouville theory, where it exhibits a strong parallel to the finite-dimensional representation theory of quantum groups. Recently from the construction of the positive representations, a direct analytic relation between modular duality and Langlands duality is also discovered, which should have deep consequences in the Langlands program.
