Some properties of the intersection graph for finite commutative principal ideal rings
Summary: Let \(R\) be a commutative finite principal ideal ring with unity, and let \(G(R)\) be the simple graph consisting of nontrivial proper ideals of \(R\) as vertices such that two vertices \(I\) and \(J\) are adjacent if they have nonzero intersection. In this paper we continue the work done by Abu Osba. We calculate the radius, eccentricity, domination number, independence number, geodetic number, and the hull number for this graph. We also determine when \(G(R)\) is chordal. Finally, we study some properties of the complement graph of \(G(R)\).
