从Macdonald多项式到A型以外的电荷统计量

From Macdonald Polynomials to a Charge Statistic beyond Type A

Cristian Lenart

摘要:

电荷是一个复杂的字统计,由于Lascoux和Schutzenberger,它给出了积极的组合公式Lusztig的q模拟的重量多重性和能量函数的仿射晶体,都是A型。由于这些概念是为所有李类型定义的,因此基于电荷的推广来表达它们一直是一个长期存在的问题。我提出了一种方法来解决这个问题,在经典的李型,最近的Ram-Yip公式的Macdonald多项式和量子Bruhat顺序相应的外尔群的基础上。该方法的细节在A型(我们恢复经典电荷)和C型(我们定义一个新的统计量)中进行。

英文摘要:

The charge is an intricate statistic on words, due to Lascoux and Schutzenberger, which gives positive combinatorial formulas for Lusztig's q-analogue of weight multiplicities and the energy function on affine crystals, both of type A. As these concepts are defined for all Lie types, it has been a long-standing problem to express them based on a generalization of charge. I present a method for addressing this problem in classical Lie types, based on the recent Ram-Yip formula for Macdonald polynomials and the quantum Bruhat order on the corresponding Weyl group. The details of the method are carried out in type A (where we recover the classical charge) and type C (where we define a new statistic).
