On the density, chromatic number and chromatic index of a graph

Abstract

Bounds on the chromatic number of a graph in terms of its density are surveyed. The concepts of line-graph and of chromatic index are exploited. In turn, a sharpening of Vizing's Theorem ls exhibited. Additional conditions yield the chromatic class of the Generalized Petersen Graphs and of certain uniquely colourable graphs.
