Diameter Thresholds of Random Cayley Graphs
Demetres Christofides, Klas Markström, Christina Savvidou
Given a group , the model denotes the probability space of all Cayley graphs of where each element of is included in the generating set independently…
Enumeration of super-strong Wilf equivalence classes of permutations in the generalized factor order
Ioannis Michos, Christina Savvidou
Super-strong Wilf equivalence classes of the symmetric group on letters, with respect to the generalized factor order, were shown by Hadjiloucas, Michos and Sa…
On super-strong Wilf equivalence classes of permutations
Demetris Hadjiloucas, Ioannis Michos, Christina Savvidou
Super-strong (elsewhere referred to as strong) Wilf equivalence is a type of Wilf equivalence on words that was introduced by Kitaev et al. in 2009. We provide a necessary and suff…
A symmetric unimodal decomposition of the derangement polynomial of type
Christos A. Athanasiadis, Christina Savvidou
The derangement polynomial for the symmetric group enumerates derangements by the number of excedances. The derangement polynomial 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 -polynomial, in the sense of Stanley,…
The local -vector of the cluster subdivision of a simplex
Christos A. Athanasiadis, Christina Savvidou
The cluster complex is an abstract simplicial complex, introduced by Fomin and Zelevinsky for a finite root system . The positive part of naturally defines a simpl…
Face numbers of cubical barycentric subdivisions
Christina Savvidou
The cubical barycentric subdivision sd_c(K) of a cubical complex K is introduced as an analogue of the barycentric subdivision of a simplicial complex. Explicit formulas for the sh…
