Abstract
The rings considered in this article are commutative with identity which are not integral domains. Let R be a ring. Let Z(R) denote the set of all zero-divisors of R and let us denote \(Z(R)\backslash \{0\}\) by \(Z(R)^{*}\). Let R be a ring such that \(Z(R)^{*}\ne \emptyset \). With R, Alen Duric et al. (J Algebra Appl, 2019. https://doi.org/10.1142/S0219498819501901) introduced and investigated an undirected graph denoted by ZT(R) whose vertex set is \(Z(R)^{*}\) and distinct vertices x and y are adjacent in ZT(R) if and only if \(xy = 0\) and \(x + y\in Z(R)\). Let \((ZT(R))^{c}\) denote the complement of ZT(R). In this article, we determine when \((ZT(R))^{c}\) is connected and in the case \((ZT(R))^{c}\) is connected, we determine the diameter and radius of \((ZT(R))^{c}\).
