利用Littelmann [2], [4] 和叶家琛与周忠国 [5] 所给出的结果和所使用的方法, 本文首先给出了Cl型复单李代数gl的普遍包络代数U(g l)的整形式的一组单项式基, 并构造了它的子代数的一个滤链. 在此基础上, 本文得到了U(g l)的 Weyl 模 V(λ) 的整形式的一组新基以及计算其权空间维数的一个新的重数公式.

Global and local Weyl modules for the untwisted multiloop Lie algebras were defined in [CFK] via homological properties. In this paper we extended the ideas to give a categorical definition of the Wey...
