Counting Descent Pairs with Prescribed Colors in the Colored Permutation
Groups
Abstract.
We define new statistics,
(c,d)-descents, on the colored permutation groups
Zr wreath Sn
and compute the distribution of these
statistics on the elements in these groups. We use some
combinatorial approaches, recurrences, and generating functions
manipulations to obtain our results.
