交换环II上模的Zapriki拓扑图

The Zariski topology-graph of modules over commutative rings II

Habibollah Ansari-Toroghy, Shokoufeh Habibi

摘要:

设$M$是交换环$R$上的模.本文继续研究了在(The Zki topology-graph of modules over交换环,Comm. Algebra.,42(2014),3283- 3296)。对于$Spec(M)$的非空子集$T$,我们得到了$G(τ_T)$是二部图的那些模块$M$的有用的特征。证明了如果$G(τ_T)$是树,则$G(τ_T)$是星图.此外,我们还研究了Zebriki拓扑图的着色问题,并研究了$χ(G(τ_T))$和$ω(G(τ_T))$之间的相互影响.

英文摘要:

Let $M$ be a module over a commutative ring $R$. In this paper, we continue our study about the Zariski topology-graph $G(τ_T)$ which was introduced in (The Zariski topology-graph of modules over commutative rings, Comm. Algebra., 42 (2014), 3283--3296). For a non-empty subset $T$ of $Spec(M)$, we obtain useful characterizations for those modules $M$ for which $G(τ_T)$ is a bipartite graph. Also, we prove that if $G(τ_T)$ is a tree, then $G(τ_T)$ is a star graph. Moreover, we study coloring of Zariski topology-graphs and investigate the interplay between $χ(G(τ_T))$ and $ω(G(τ_T))$.
