On the Terwilliger algebra of the group association scheme of the symmetric group $sym (7)$

Allen Herman, Roghayeh Maleki, Andriaherimanana Sarobidy Razafimahatratra

Terwilliger algebras are finite-dimensional semisimple algebras that were first introduced by Paul Terwilliger in 1992 in studies of association schemes and distance-regular graphs…

On the $Q$ -polynomial property of the full bipartite graph of a Hamming graph

Blas Fernández, Roghayeh Maleki, Štefko Miklavič +1

The $Q$ -polynomial property is an algebraic property of distance-regular graphs, that was introduced by Delsarte in his study of coding theory. Many distance-regular graphs admit t…

On the maximum intersecting sets of the general semilinear group of degree $2$

Roghayeh Maleki, Andriaherimanana Sarobidy Razafimahatratra

Let $p$ be a prime and $q = p^{k}$ . A subset $F \subset ΓL_{2} (q)$ is intersecting if any two semilinear transformations in $F$ agree on some non-z…
