A harmonious coloring of a simple graph G is a proper vertex coloring such that each pair of colors appears together on at most one edge. The harmonious chromatic number h(G) is the least number of colors in such a coloring. We obtain a new upper bound for the harmonious chromatic number of general

It is well known that almost every graph in the random space G(n, p) has chromatic number of order O(np/ log(np)), but it is not clear how we can recognize such graphs without eventually computing the chromatic numbers, which is NP-hard. The first goal of this article is to show that the above-menti
We show that coloring the edges of a multigraph G in a particular order often leads to improved upper bounds for the chromatic index Ο (G). Applying this to simple graphs, we significantly generalize recent conditions based on the core of G (i.e., the subgraph of G induced by the vertices of degree
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
The interval number of a graph G, denoted by i(G), is the least natural number t such that G is the intersection graph of sets, each of which is the union of at most t intervals. Here we settle a conjecture of Griggs and West about bounding i(G) in terms of e, that is, the number of edges in G. Name
Let G = (V, E) be a graph and let k be a nonnegative integer. A vector c β Z V + is called k-colorable iff there exists a coloring of G with k colors that assigns exactly c(v) colors to vertex v β V . Denote by Ο(G) and Ο f (G) the chromatic number and fractional chromatic number, respectively. We p
