- Abstract
Let R be a commutative ring with unity 1≠0. In this paper, we completely describe the vertex and the edge chromatic number of the compressed zero divisor graph of the ring of integers modulo n. We find the clique number of the compressed zero divisor graph ΓE(Zn) of Zn and show that ΓE(Zn) is weakly perfect. We also show that the edge chromatic number of ΓE(Zn) is equal to the largest degree proving that ΓE(Zn) resides in class 1 family of graphs.
