关于符号图的幂

On the Powers of Signed Graphs

Shijin T, Germina K A, Shahul Hameed K

摘要:

带符号图是序偶$Σ=(G,σ),$,其中$G=(V,E)$是具有签名函数$σ:E\rightarrow \{1,-1\}$的$Σ$的底层图。本文定义了符号图的$n^{th}$幂,并讨论了符号图的这些幂的一些性质。由于我们可以定义两种类型的符号图作为符号图的幂,给出了符号图的$n^{th}$幂唯一的充要条件.此外,我们还刻画了平衡幂符号图。

英文摘要:

A signed graph is an ordered pair $Σ=(G,σ),$ where $G=(V,E)$ is the underlying graph of $Σ$ with a signature function $σ:E\rightarrow \{1,-1\}$. In this article, we define $n^{th}$ power of a signed graph and discuss some properties of these powers of signed graphs. As we can define two types of signed graphs as the power of a signed graph, necessary and sufficient conditions are given for an $n^{th}$ power of a signed graph to be unique. Also, we characterize balanced power signed graphs.
