Authors
Afkhami, M.
Abstract
Let (P,≤) be a partially ordered set with a least element 0. In this paper, we define and study the cozero-divisor graph of P, which is an (undirected) graph with vertex-set P\{0}, and two distinct vertices x and y are adjacent if and only if x ∊ {y}e and y ∊ {x}e, where for a vertex z, {z}e denotes the set of lower bounds of z.
