On the zero-divisor graph of finite commutative ring

Apstrakt: This talk is going to be on the zero divisor graph Γ(G) of a finite commutative ring with unity. I will give its definition and some concepts like the distance between two vertices, the diameter of a graph G, the girth of G, and the meaning of an annihilator. Through some theorems I will give properties of Γ(G). Also I will mention Zariski topology under the section named as [The spectrum of a commutative ring R], as I will give the relation between Gelfand ring and spectrum of R. In the finally talk I will mention cycles in the zero-divisor graph and its connection with a reduced ring R.
