Abstract
Let be a commutative ring with identity, and let be the set of zero-divisors of . The annihilator graph of is defined as the undirected graph with the vertex set , and two distinct vertices and are adjacent if and only if . In this paper, all rings whose annihilator graphs can be embed on the plane or torus are classified.
