Abstract:

A total k-coloring of a graph G is a coloring of V (G) boolean OR E(G) using k colors such that no two adjacent or incident elements receive the same color. The total chromatic number chi ''(G) is the smallest integer k such that G has a total k-coloring. In this paper, it is proved that the total chromatic number of any graph G embedded in a surface Sigma of Euler characteristic chi(Sigma) >= 0 is Delta(G) + 1 if Delta >= 10, where Delta(G) denotes the maximum degree of G.
