TITLEStudent Seminar in Combinatorial Commutative Algebra:The Zero-Divisor Graph of Commutative Rings

ABSTRACT For a commutative ring R we associated a graph, whose vertices are the non-zero zero-divisors of R and whose edges connect two vertices x and y if and only if x*y=0. We pay attention to the relationship between the ring-theoretic properties of R and the graph-theoretic properties of its zero-divisor graph.
