关于$A$型局部Weyl模的Chari-Loktev基

On Chari-Loktev bases for local Weyl modules in type $A$

K. N. Raghavan, B. Ravinder, Sankaran Viswanath

摘要:

本文研究了Chari-Loktev为一类特殊线性李代数的当前代数的局部Weyl模引入的基.分区覆盖模式,简称POP-其介绍是本文的目的之一-形成这些基础的方便参数化集。它们所起的作用类似于特殊线性李代数的表示论中的(Gelfand-Tsetlin)模式所起的作用。POP的概念自然地引出了模式的面积的概念。我们观察到,有一个唯一的模式,最大面积之间的所有这些与给定的边界序列和给定的权重。我们给出了一个组合的证明,并讨论其表示理论的相关性。然后,我们提出了一个关于“稳定性”的猜想,即,相容性的长期范围内,Chari-Loktev基地方面的包容性的地方Weyl模块。为了说明这个猜想,我们在有色分区和持久性有机污染物之间建立了某种双射,这本身可能是有趣的。

英文摘要:

This paper is a study of the bases introduced by Chari-Loktev for local Weyl modules of the current algebra associated to a special linear Lie algebra. Partition overlaid patterns, POPs for short---whose introduction is one of the aims of this paper---form convenient parametrizing sets of these bases. They play a role analogous to that played by (Gelfand-Tsetlin) patterns in the representation theory of the special linear Lie algebra. The notion of a POP leads naturally to the notion of area of a pattern. We observe that there is a unique pattern of maximal area among all those with a given bounding sequence and given weight. We give a combinatorial proof of this and discuss its representation theoretic relevance. We then state a conjecture about the "stability", i.e., compatibility in the long range, of Chari-Loktev bases with respect to inclusions of local Weyl modules. In order to state the conjecture, we establish a certain bijection between colored partitions and POPs, which may be of interest in itself.
