The graphs with a symmetrical Euler cycle

Jiyong Chen, Cai Heng Li, Cheryl E. Praeger +1

The edges surrounding a face of a map $M$ form a cycle $C$ , called the boundary cycle of the face, and $C$ is often not a simple cycle. If the map $M$ is arc-transitive, then there…

Skew-morphisms of nonabelian characteristically simple groups

Jiyong Chen, Shaofei Du, Cai Heng Li

A skew-morphism of a finite group $G$ is a permutation $\s$ on $G$ fixing the identity element, and for which there exists an integer function $π$ on $G$ such that $\s(xy)=\s(x)\s^…

Characterization of subgroup perfect codes in Cayley graphs

Jiyong Chen, Yanpeng Wang, Binzhou Xia

A subset $C$ of the vertex set of a graph $Γ$ is called a perfect code in $Γ$ if every vertex of $Γ$ is at distance no more than $1$ to exactly one vertex of $C$ . A subset $C$ of a…
