我们给出了一种表示与量子 Kac-Moody 代数的可积最高权模相对应的晶体(基)的通用方法,称为多面体实现。这用于明确描述任意阶 2 Kac-Moody 代数情况、经典 A_n-情况和仿射 A^{(1)}_{n-1}-情况的可积最高权重模块的晶体基。
We give a general way of representing the crystal (base) corresponding to the intgrable highest weight modules of quantum Kac-Moody algebras, which is called polyhedral realizations. This is applied to describe explicitly the crystal bases of integrable highest weight modules for arbitrary rank 2 Kac-Moody algebra cases, the classical A_n-case and the affine A^{(1)}_{n-1}-case.
