Abstract

Let m,n>1m, n > 1 be two integers, and Zn\mathbb{Z}_n be a Zm\mathbb{Z}_m-module. Let I(Zm)I(\mathbb{Z}_m)^* be the set of all non- zero proper ideals of Zm\mathbb{Z}_m. The Zn\mathbb{Z}_n-intersection graph of Zm\mathbb{Z}_m, denoted by Gn(Zm)G_n(\mathbb{Z}_m) is a graph with the vertex set I(Zm)I(\mathbb{Z}_m)^*, and two distinct vertices II and JJ are adjacent if and only if IZnJZn0I\mathbb{Z}_n\cap J\mathbb{Z}_n\neq 0. In this paper, we determine the values of mm and nn for which Gn(Zm)G_n(\mathbb{Z}_m) is planar, outerplanar or ring graph.
