超八面体群的下降数和主指数

Descent Numbers and Major Indices for the Hyperoctahedral Group

Ron M. Adin, Francesco Brenti, Yuval Roichman

摘要:

引入并研究了超八面体群$B_{n}$上的三个新统计量,证明了它们给出了$S_{n}$上下降数和较多指数的Carlitz恒等式的两个推广.这回答了Foata提出的一个问题。

英文摘要:

We introduce and study three new statistics on the hyperoctahedral group $B_{n}$, and show that they give two generalizations of Carlitz's identity for the descent number and major index over $S_{n}$. This answers a question posed by Foata.
