路与Kostka-Macdonald多项式

Paths and Kostka--Macdonald Polynomials

Anatol N. Kirillov, Reiho Sakamoto

摘要:

我们给出了盒球系统状态空间的几种等价组合描述,并将这些模型的某些分拆函数与李代数gl(n)的基本表示的张量积的q权重数联系起来.作为应用,我们给出了Haglund-Haiman-Loehr公式在t=1时的一个初等证明.此外,我们提出了一类新的组合统计,自然推广所谓的能量统计。

英文摘要:

We give several equivalent combinatorial descriptions of the space of states for the box-ball systems, and connect certain partition functions for these models with the q-weight multiplicities of the tensor product of the fundamental representations of the Lie algebra gl(n). As an application, we give an elementary proof of the special case t=1 of the Haglund--Haiman--Loehr formula. Also, we propose a new class of combinatorial statistics that naturally generalize the so-called energy statistics.
