On subgroup perfect codes in Cayley sum graphs

Jun-Yang Zhang

A perfect code $C$ in a graph $Γ$ is an independent set of vertices of $Γ$ such that every vertex outside of $C$ is adjacent to a unique vertex in $C$ , and a total perfect code $C$ …

Skew-Morphisms of Elementary Abelian p-Groups

Shaofei Du, Wenjuan Luo, Hao Yu +1

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

Flow modules and nowhere-zero flows

Jun-Yang Zhang, Na Lu

Let $Γ$ be a graph, $A$ an abelian group, $D$ a given orientation of $Γ$ and $R$ a unital subring of the endomorphism ring of $A$ . It is shown that the set of all maps $φ…

Smooth skew-morphisms of the dihedral groups

Naer Wang, Kan Hu, Kai Yuan +1

A skew-morphism $φ$ of a finite group $A$ is a permutation on $A$ such that $φ (1) = 1$ and $φ (x y) = φ (x) φ^{π (x)} (y)$ for all $x, y \in A$ where $π : A \to Z_{∣ φ ∣}$ is an integer fun…

Scanning tunneling microscopy and spectroscopy of twisted trilayer graphene

Wei-Jie Zuo, Jia-Bin Qiao, Dong-Lin Ma +5

Twist, as a simple and unique degree of freedom, could lead to enormous novel quantum phenomena in bilayer graphene. A small rotation angle introduces low-energy van Hove singulari…
