Abstract

Let R be a commutative ring. The zero-divisor graph of R is the

(simple) graph 􀀀(R) with vertices the nonzero zero-divisors of R, and two

distinct vertices x and y are adjacent if and only if xy = 0. In this article, we

investigate 􀀀(R) when R does not have an identity, and we determine all such

zero-divisor graphs with 14 or fewer vertices.

Keywords
