Given a group and a subgroup , a set is called \emph{-intersecting} if for any , there exists such that $…
On the intersection density of the symmetric group acting on uniform subsets of small size
Angelot Behajaina, Roghayeh Maleki, Andriaherimanana Sarobidy Razafimahatratra
Given a finite transitive group , a subset of is \emph{intersecting} if any two elements of agree on some element of $Ω…
Erdős-Ko-Rado results for the general linear group, the special linear group and the affine general linear group
Karen Meagher, A. Sarobidy Razafimahatratra
In this paper, we show that both the general linear group $\gl{q}$ and the special linear group $\slg{q}$ have both the EKR property and the EKR-module property. This is done using…
On non-normal subgroup perfect codes

Let be a graph. A subset is a \emph{perfect code} of if is a coclique of with the property that any vertex in is adjace…

Roghayeh Maleki, Andriaherimanana Sarobidy Razafimahatratra
In 2020, Siemons and Zalesski [On the second eigenvalue of some Cayley graphs of the symmetric group. {\it arXiv preprint arXiv:2012.12460}, 2020] determined the second eigenvalue…
On multipartite derangement graphs
Andriaherimanana Sarobidy Razafimahatratra
Given a finite transitive permutation group , with , the derangement graph of is the Cayley graph $\operatorname{Cay}(G,\operatorn…
