On The Zero Divisor Graph of Z p n

Let R be a commutative ring. We used Z(R)* to denote the set of nonzero zero divisors of R. We associate a graph ?(R) to R with vertices Z(R)* and for distinct a , b ? Z(R) the vertices a , b are adjacent if and only ab = 0. In this paper we obtain diameter, clique number, minimum and maximum degree of graph ? (Z p n ).
