On the Clean Graph of a Ring

Combinatorics 2023-01-24 v1

Abstract

Let R be a ring (not necessarily commutative ring) with identity. The clean graph Cl(R) of a ring R is a graph with vertices in the form of ordered pair (e; u), where e is an idempotent of the ring R and u is a unit of the ring R. Two distinct vertices (e; u) and (f; v) are adjacent if and only if ef = fe = 0 or uv = vu = 1. In this paper, we determine the Wiener index, Matching number of the clean graph of the ring Zn.
