Zhou, H., The chromatic difference sequence of the Cartesian product of graphs, Discrete Mathematics 90 (1991) 297-311. The chromatic difference sequence cds(G) of a graph G with chromatic number n is defined by cds(G) = (a(l), a(2), . . , a(n)) if the sum of a(l), a(2), . , a(t) is the maximum numb
In the paper we obtain some conditions under which the binding number bind (C) of a Cartesian product graph G is equal to The concept of the binding number of a graph was introduced by Woodall in 1973 . The main theorem of Woodall's paper is a sufficient condition for the existence of a Hamiltonian
Colorings of disk graphs arise in the study of the frequency-assignment problem in broadcast networks. Motivated by the observations that the chromatic number of graphs modeling real networks hardly exceeds their clique number, we examine the related properties of the unit disk (UD) graphs and their
A cube-like graph is a graph whose vertices are all 2" subsets of a set E of cardinality n, in which two vertices are adjacent if their symmetric difference is a member of a given specified collection of subsets of E. Many authors were interested in the chromatic number of such graphs and thought it
