Let f (v, e, Ξ») denote the maximum number of proper vertex colorings of a graph with v vertices and e edges in Ξ» colors. In this paper we present some new upper bounds for f (v, e, Ξ»). In particular, a new notion of pseudoproper colorings of a graph is given, which allows us to significantly improve

## Abstract A __polychromatic k__β__coloring__ of a plane graph __G__ is an assignment of __k__ colors to the vertices of __G__ such that every face of __G__ has __all k__ colors on its boundary. For a given plane graph __G__, one seeks the __maximum__ number __k__ such that __G__ admits a polychro
Motivated by the work of NeΕ‘etΕil and R ΓΆdl on "Partitions of vertices" we are interested in obtaining some quantitative extensions of their result. In particular, given a natural number r and a graph G of order m with odd girth g, we show the existence of a graph H with odd girth at least g and ord
Lawrence [2, Theorem 3] and Borodin and Kostochka [1, Lemma 2' 1 both give the same theorem about vertex colorings of graphs (Corollary 1 below). But Lawrence's proof, although powerful, is a little long, and Borodin and Kostoehka state the result without a proof.
We prove the conjecture of Burris and Schelp: a coloring of the edges of a graph of order n such that a vertex is not incident with two edges of the same color and any two vertices are incident with different sets of colors is possible using at most n+1 colors. 1999 Academic Press ## 1. Introducti
