The Grundy number of a graph G is the maximum number k of colors used to color the vertices of G such that the coloring is proper and every vertex x colored with color i, 1 ≤ i ≤ k, is adjacent to (i − 1) vertices colored with each color j, 1 ≤ j ≤ i − 1. In this paper we give bounds for the Grundy number of some graphs and cartesian products of graphs. In(More)
