欧拉拟对称函数与循环筛分

Eulerian quasisymmetric functions and cyclic sieving

Bruce Sagan, John Shareshian, Michelle L. Wachs

摘要:

它表明,一个改进的版本的Q-类似物的欧拉数连同行动,通过共轭,所产生的对称群$S_n$的子群的$n$ -循环$(1,2,...,n)$上的固定循环类型和固定数量的超越的排列集提供了一个实例的循环筛选现象的赖纳,斯坦顿和白色。主要的工具是一类对称函数最近推出的工作中的两个作者。

英文摘要:

It is shown that a refined version of a q-analogue of the Eulerian numbers together with the action, by conjugation, of the subgroup of the symmetric group $S_n$ generated by the $n$-cycle $(1,2,...,n)$ on the set of permutations of fixed cycle type and fixed number of excedances provides an instance of the cyclic sieving phenonmenon of Reiner, Stanton and White. The main tool is a class of symmetric functions recently introduced in work of two of the authors.
