Title: Free Field Realization of Affine Kac-Moody Algebras

Speaker: Prof.  Yongchang Zhu (The Hong Kong University of Science and Technology)

Time: 3:00-4:30pm, June 25

Location: Room 200-9, Sir Shaw Run Run Business Administration building, School of Mathematical Sciences, Yuquan Campus

Abstract: Affine Kac-Moody algebras are infinite dimensional generalizations of simple Lie algebras. This class of Lie algebras is now a fundamental object studied in representation theory and plays an important role in mathematical physics. While the highest weight representations or more generally the representations in category O have been studied intensively, the representations of other types are much less studied. For example it is not known if there is a generalization of concept of (g,K)-modules. Currently we are at the stage to construct natural examples before making general definitions. In this talk, we show some new constructions using the method of free field realization
