On the Terwilliger algebras of quasi-thin Schurian association schemes
Roghayeh Maleki, Andriaherimanana Sarobidy Razafimahatratra
An association scheme is triply transitive if its automorphism group is transitive, and the centralizer algebra of a point stabilizer of its automorphism group coincides with the T…
Perfect and multiple state transfer in oriented Cayley graphs
Ada Chan, Venkata Raghu Tej Pantangi, Andriaherimanana Sarobidy Razafimahatratra +1
We study perfect state transfer and multiple state transfer in oriented normal Cayley graphs. We construct examples in a variety of groups, ranging from abelian to nonsolvable, and…
The intersection densities of transitive actions of with cyclic point stabilizers
Angelot Behajaina, Roghayeh Maleki, Andriaherimanana Sarobidy Razafimahatratra
Given a finite transitive group , the {intersection density} of is defined as the ratio between the size of the largest subsets of in which any…
The intersection density of cubic arc-transitive graphs with -arc-regular full automorphism group equal to
Karen Meagher, Andriaherimanana Sarobidy Razafimahatratra
The \emph{intersection density} of a transitive permutation group is the ratio between the largest size of a subset of in which any two agree on…
