Finite groups with coprime non-linear codegrees

Ashkan Zarezadeh, Behrooz Khosravi, Zeinab Akhlaghi

Given a finite group G with an irreducible character Ï\in Irr(G), the codegree of Ïis defined by cod(Ï) = |G :\ker Ï|/Ï(1). The set of non-linear irreducible character codegre…

Regular set in Cayley sum mgraph

F. Seiedali, B. Khosravi, Z. Akhlaghi

A subset $C$ of the vertex set of a graph $I^$ is said to be $(I^\pm, I^^{2})$ -regular if $C$ induces an $I^\pm$ -regular subgraph and every vertex outside $C$ is adjacent to exactly $I^^{2}$ vert…
