关于 Kac-Moody 代数可积模的若干结果
Some Results of the Integrable Modules of Kac Moody Algebra
【摘要】 通过对Kac-Moody代数的可积模引入连通权集的概念,得到了模的不可约和完全可约的判定定理。
【Abstract】 Letg(A) be a Kac Moody algebra over C.In this note,the set of connected weights for integrable g(A) modules is introduced.The criterions of irreducibility and complete reducibility for integrable g(A) modules are obtained when g(A) is of finite type or affine type.
