报告内容简介：In this talk, we will introduce the Gelfand-Kirillov dimension and associated variety of highest weight moudles of simple Lie algebras. By using a conjecture of Tanisaki, we will show that there is a bijection between the Kazhdan-Lusztig right cells and associated varieties of highest weight modules with infinitesimal character. In the second part, by using Lusztig's a-function we will give an algorithm to compute the Gelfand-Kirillov dimension of any highest weight module of classical type Lie algebras. Finally, we will give a characterization for the AV of highest weight Harish-Chandra modules of noncompact Lie gorups of Hermitian type. This talk is based on some joint work with Yixin Bao, Markus Hunziker, Wei Xiao, Xun Xie and Roger Zierau.
