  Abstract:
In this article, we give several generalizations of the concept of zero-divisor elements in a commutative ring with identity to modules. Then for each R-module M we associate three undirected (simple) graphs Γ*(RM) ⊆ Γ(RM) ⊆ Γ*(RM) which, for M=R all coincide with the zero-divisor graph of R. The main object of this paper is to study the interplay of module-theoretic properties of M with graph-theoretic properties of these graphs.
