Abstract
Let be a commutative ring and an ideal of . The zero-divisor graph of with respect to , denoted (), is the undirected graph whose vertex set is for some with two distinct vertices and joined by an edge when . In this paper, we extend the definition of the ideal-based zero-divisor graph to noncommutative rings.
