Edgewise subdivisions, local $h$ -polynomials and excedances in the wreath product $\ZZ_r \wr \mathfrak{S}_n$

Christos A. Athanasiadis

The coefficients of the local $h$ -polynomial of the barycentric subdivision of the simplex with $n$ vertices are known to count derangements in the symmetric group $S_{n}$ …

A symmetric unimodal decomposition of the derangement polynomial of type $B$

Christos A. Athanasiadis, Christina Savvidou

The derangement polynomial $d_{n} (x)$ for the symmetric group enumerates derangements by the number of excedances. The derangement polynomial $d_{n}^{B} (x)$ for the hyperoctahedral grou…
