Abstract

A modular k-coloring, k ≥ 2, of a graph G is a coloring of the vertices of G with the elements in Z k having the property that for every two adjacent vertices of G, the sums of the colors of their neighbors are different in Z k . The minimum k for which G has a modular k-coloring is the modular chromatic number of G. In this paper, except for some special cases, modular chromatic number of C m   C n is determined.
