$GL_n$型Macdonald多项式的Monk定则

Monk rules for type $GL_n$ Macdonald polynomials

Tom Halverson, Arun Ram

摘要:

本文给出了麦克唐纳多项式的Monk规则,它类似于舒伯特多项式的Monk规则。这些公式类似于Baratta(2008)给出的公式,但我们的推导方法是使用Cherednik的interwiners。通过这种技术推导蒙克规则解决了Baratta的工作和Yip(2010)的乘积公式之间的关系。Monk公式在$q=0$和/或$t=0$上的专门化为Iwahori球面多项式以及有限和仿射键多项式提供了Monk规则。

英文摘要:

In this paper we give Monk rules for Macdonald polynomials which are analogous to the Monk rules for Schubert polynomials. These formulas are similar to the formulas given by Baratta (2008), but our method of derivation is to use Cherednik's interwiners. Deriving Monk rules by this technique addresses the relationship between the work of Baratta and the product formulas of Yip (2010). Specializations of the Monk formula's at $q=0$ and/or $t=0$ provide Monk rules for Iwahori-spherical polynomials and for finite and affine key polynomials.
