Diameter Thresholds of Random Cayley Graphs

Demetres Christofides, Klas Markström, Christina Savvidou

Given a group $G$ , the model $G (G, p)$ denotes the probability space of all Cayley graphs of $G$ where each element of $G$ is included in the generating set independently…

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…

Barycentric subdivisions and derangement polynomials for the even-signed permutation groups

Christina Savvidou

The derangement polynomial for the symmetric group enumerates derangements by the number of excedances. It can be interpreted as the local $h$ -polynomial, in the sense of Stanley,…
