Abstract

Let R be a commutative ring with identity, and let I be an ideal of R. The zero-divisor graph of R with respect to I, denoted by ΓI(R)\Gamma_I(R), is the graph whose vertices are the set {xRIxyI\{x \in R \setminus I | xy \in I for some yRI}y \in R \setminus I\}, where distinct vertices x and y are adjacent if and only if xyIxy \in I. The cozero-divisor graph with respect to I, denoted by ΓI(R)\Gamma''_I(R), is the graph of RR with vertices {xRIxR+IR}\{x \in R \setminus I | xR + I \neq R\}, and two distinct vertices x and y are adjacent if and only if xyR+Ix \notin yR + I and yxR+Iy \notin xR + I. In this paper, we introduce and investigate an undirected graph QΓI(R)Q\Gamma''_I(R) of R with vertices {xRIxR+IR\{x \in R \setminus \sqrt{I} | xR + I \neq R and xR+I=xR+I}xR + \sqrt{I} = xR + I\} and two distinct vertices x and y are adjacent if and only if xyR+Ix \notin yR + I and yxR+Iy \notin xR + I.
