Abstract
Let R be a noncommutative ring. The zero-divisor graph of R,
denoted by Γ(R), is the (directed) graph with vertices Z(R)∗ = Z(R)−
{0}, the set of nonzero zero-divisors of R, and for distinct x, y ∈ Z(R)∗,
there is an edge x → y if and only if xy = 0. In this paper we investigate
the zero-divisor graph of triangular matrix rings over commutative rings.
