Zhanqiang Bai, Wei Xiao, Xun Xie

摘要:

本文给出了经典外尔群上Lusztig $ \mathbf{a}$ -函数的一个统一公式.在此基础上,我们得到了经典李代数单最高权模的Gelfand-Kirillov维数的一个有效算法,其最高权不一定是正则的或整数的.为了处理类型$ D $,我们证明了一个有趣的性质多米诺骨牌tableaux通过引入一个不变量,称为空心tableau。作为一个应用,明确地确定了所有简单最高权Harish-Chandra模的相关簇,包括例外情况.

英文摘要:

In this paper, we present a uniform formula of Lusztig's $ \mathbf{a}$-functions on classical Weyl groups. Then we obtain an efficient algorithm for the Gelfand-Kirillov dimensions of simple highest weight modules of classical Lie algebras, whose highest weight is not necessarily regular or integral. To deal with type $ D $, we prove an interesting property about domino tableaux by introducing an invariant, called the hollow tableau. As an application, the associated varieties of all the simple highest weight Harish-Chandra modules are explicitly determined, including the exceptional cases.
