Regular sets in Cayley sum graphs on generalized dicyclic groups

Meiqi Peng, Yuefeng Yang

For a graph $\Gamma =(V(\Gamma ),E(\Gamma ))$, a subset $C$ of $V(\Gamma )$ is called an $(\alpha ,\beta )$-regular set in $\Gamma$, if every vertex of $C$ is adjacent to exactly $\alpha$ vertices of $C$ and every vertex of $…
