Let 𝑅 be a commutative ring and 𝐼 an ideal of 𝑅 . The zero-divisor graph of 𝑅 with respect to 𝐼 , denoted Ξ“ 𝐼 ( 𝑅 ), is the undirected graph whose vertex set is { π‘₯ ∈ 𝑅 ⧡ 𝐼 | π‘₯ 𝑦 ∈ 𝐼 for some 𝑦 ∈ 𝑅 ⧡ 𝐼 } with two distinct vertices π‘₯ and 𝑦 joined by an edge when π‘₯ 𝑦 ∈ 𝐼 . In this paper, we extend the definition of the ideal-based zero-divisor graph to noncommutative rings.
