极权投影器II

Extremal weight projectors II

Hoel Queffelec, Paul Wedrich

摘要:

在以前的工作中,我们构造了Temperley-Lieb范畴的仿射扩张中的图幂等元,它描述了sl(2)的极值权投影,并将第一类切比雪夫多项式分类。本文将极权投影的构造推广到gl(N)的情形,其中N大于或等于2,目的是通过Khovanov-Rozansky链同调对相应的torus skein代数进行分类.作为副产品,我们得到了兼容的图形表示的gl(N)和它的Cartan子代数的表示范畴,和一个分类的幂和对称多项式。

英文摘要:

In previous work, we have constructed diagrammatic idempotents in an affine extension of the Temperley-Lieb category, which describe extremal weight projectors for sl(2), and which categorify Chebyshev polynomials of the first kind. In this paper, we generalize the construction of extremal weight projectors to the case of gl(N) for N greater than or equal to 2, with a view towards categorifying the corresponding torus skein algebras via Khovanov-Rozansky link homology. As by-products, we obtain compatible diagrammatic presentations of the representation categories of gl(N) and its Cartan subalgebra, and a categorification of power-sum symmetric polynomials.
