k-Schur函数的Murnaghan-Nakayama规则

The Murnaghan-Nakayama rule for k-Schur functions

Jason Bandlow, Anne Schilling, Mike Zabrocki

摘要:

证明了Lapointe和Morse的$k$ -Schur函数的Murgnaghan-Nakayama定则,即给出了幂和对称函数与$k$-Schur函数乘积关于$k$-Schur函数的展开式的显式公式.这是证明使用非交换的$k$ -Schur函数的nilCoxeter代数引进的林和仿射模拟的非交换对称函数的Fomin和格林。

英文摘要:

We prove the Murgnaghan--Nakayama rule for $k$-Schur functions of Lapointe and Morse, that is, we give an explicit formula for the expansion of the product of a power sum symmetric function and a $k$-Schur function in terms of $k$-Schur functions. This is proved using the noncommutative $k$-Schur functions in terms of the nilCoxeter algebra introduced by Lam and the affine analogue of noncommutative symmetric functions of Fomin and Greene.
