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…

On the subgroup regular set in Cayley graphs

Asamin Khaefi, Zeinab Akhlaghi, Behrooz Khosravi

A subset $C$ of the vertex set of a graph $I^$ is said to be $(a, b)$ -regular if $C$ induces an $a$ -regular subgraph and every vertex outside $C$ is adjacent to exactly $b$ vertices…
