On kernel isomorphisms of $m$ -Cayley digraphs and finite $2$ PCI-groups

Xing Zhang, Yan-Quan Feng, Jin-Xin Zhou +1

The isomorphism problem for digraphs is a fundamental problem in graph theory. In this paper, we consider this problem for $m$ -Cayley digraphs which are generalization of Cayley di…

Normal and non-normal Cayley digraphs on cyclic and dihedral groups

Jun-Feng Yang, Yan-Quan Feng, Fu-Gang Yin +1

A Cayley digraph on a group $G$ is called NNN if the Cayley digraph is normal and its automorphism group contains a non-normal regular subgroup isomorphic to $G$ . A group is called…

Symmetric Cayley graphs on non-abelian simple groups of valency 7

Xing Zhang, Yan-Quan Feng, Fu-Gang Yin +1

Let $I^$ be a connected $7$ -valent symmetric Cayley graph on a finite non-abelian simple group $G$ . If $I^$ is not normal, Li {\em et al.} [On 7-valent symmetric Cayley graphs of f…
