任意秩为2的修正量子代数的晶基多面体实现

Polyhedral Realizations of Crystal Bases for Modified Quantum Algebras of Arbitrary Rank 2 Cases

Ayumu Hoshino

摘要:

我们描述了修正量子代数的晶体基,并给出了任意秩为2的情形下,其包含单位元的连通分支$B_0(λ)$的最高(或最低)权向量的显式表达式.通过多面体实现方法,给出了包含最高(或最低)权向量的$B_0(λ)$的显式形式。

英文摘要:

We describe the crystal bases of the modified quantum algebras and give the explicit form of the highest (or lowest) weight vector of its connected component $B_0(λ)$ containing the unit element for arbitrary rank 2 cases. We also present the explicit form of $B_0(λ)$ containing the highest (or lowest) weight vector by the polyhedral realization method.
