0-布尔代数的Stanley-Reisner环上的Hecke代数作用

0-Hecke algebra action on the Stanley-Reisner ring of the Boolean algebra

Jia Huang

摘要:

定义了A型0-Hecke代数在布尔代数的Stanley-Reisner环上的作用.通过研究这一行动,我们得到了一个家庭的多元非交换对称函数,专门的非交换Hall-Littlewood对称函数和他们的(q,t)-类似物介绍了Bergeron和Zabrocki,和一个更一般的家庭的非交换对称函数的参数与路径在二叉树介绍最近由Lascoux,Novelli,和Thibon。我们还得到多元拟对称函数的身份,专门的结果Garsia和Gessel的生成函数的多元分布的排列统计。

英文摘要:

We define an action of the 0-Hecke algebra of type A on the Stanley-Reisner ring of the Boolean algebra. By studying this action we obtain a family of multivariate noncommutative symmetric functions, which specialize to the noncommutative Hall-Littlewood symmetric functions and their (q,t)-analogues introduced by Bergeron and Zabrocki, and to a more general family of noncommutative symmetric functions having parameters associated with paths in binary trees introduced recently by Lascoux, Novelli, and Thibon. We also obtain multivariate quasisymmetric function identities, which specialize to results of Garsia and Gessel on generating functions of multivariate distributions of permutation statistics.
