The n-total graph of a commutative ring

Abstract

Let $R$ be a commutative ring with $1\ne 0$, $Z(R)$ be the set of all zero-divisors of $R$, and $n\ge 1$. This paper introduces the $n$-total graph of a commutative ring $R$. The $n$-total graph of a commutative ring $R$, denoted by $n-T(R)$, is an undirected simple graph with vertex set $R$, such that two vertices $x,y$ in $R$ are connected by an edge if $x^n+y^n$ in $Z(R)$. Note that if $n=1$, then the $1$-total graph of $R$ is the total graph of $R$ in the sense of Anderson-Badawi's paper on the total graph of a commutative ring. In this paper, we study some graph properties and theoretical ring structure.
