Descent Numbers and Major Indices for the Hyperoctahedral Group

Combinatorics 2007-05-23 v1

Abstract

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