亏格为1(非)可定向的非循环图

Non-cyclic graphs of (non)orientable genus one

Xuanlong Ma

摘要:

设$G$是有限非循环群. $G$的非循环图$Γ_G$是其顶点集为$G\setminus Cyc(G)$的图,如果两个不同的顶点不生成循环子群,则它们相邻,其中$Cyc(G)=\{a\in G: \langle a,b\rangle\ \text{is cyclic for each } b\in G\}$。本文对有限非循环群$G$进行了分类,使得$Γ_G$有(非)可定向亏格.

英文摘要:

Let $G$ be a finite non-cyclic group. The non-cyclic graph $Γ_G$ of $G$ is the graph whose vertex set is $G\setminus Cyc(G)$, two distinct vertices being adjacent if they do not generate a cyclic subgroup, where $Cyc(G)=\{a\in G: \langle a,b\rangle\ \text{is cyclic for each } b\in G\}$. In this paper, we classify all finite non-cyclic groups $G$ such that $Γ_G$ has (non)orientable genus one.
