AI总结:

本文通过量子幂零子代数晶体扩展为仿射晶体,给出了极小节点下 E_n^(1) 型 Kirillov-Reshetikhin 晶体 B^{r,s} 的组合实现。

摘要:

本文的主要目的是给出极小节点 r 且 s ≥ 1 时 E_n^(1) 型 Kirillov-Reshetikhin(简称 KR)晶体 B^{r,s} 的组合实现。为此,我们显式描述了与第 r 个基本权负值平移相关联的量子幂零子代数的晶体。该晶体可扩展为仿射晶体,其中由 ε_r^* 统计量刻画的某子晶体作为仿射晶体与 B^{r,s} 同构,ε_r^* 也通过三重和四重路径精确实现。

英文摘要:

The main purpose of this paper is to give a combinatorial realization of Kirillov-Reshetikhin (KR simply) crystals $B^{r, s}$ for type $\text{E}_n^{(1)}$ with a minuscule node $r$ and $s \ge 1$. To do this, we describe explicitly the crystal of the quantum nilpotent subalgebra associated with the translation by the negative of the $r$-th fundamental weight. Then the crystal can be extended as an affine crystal, in which a certain subcrystal characterized by the $\varepsilon_r^*$-statistic is isomorphic to $B^{r,s}$ as an affine crystal, where $\varepsilon_r^*$ is also realized precisely in terms of triple and quadruple paths.
