Statistics on the Multi-Colored Permutation Groups

Download www3.combinatorics.org

We deﬁne an excedance number for the multi-colored permutation group i.e. the wreath product (Zr1 × · · · × Zrk ) Sn and calculate its multi-distribution with some natural parameters. We also compute the multi-distribution of the parameters exc(π) and ﬁx(π) over the sets of involutions in the multi-colored permutation group. Using this, we count the number of involutions in this group having a ﬁxed number of excedances and absolute ﬁxed points.
