Abstract

Let Ξ»(G) be the line‐distinguishing chromatic number and xβ€²(G) the chromatic index of a graph G.

We prove the relation Ξ»(G) β‰₯ xβ€²(G), conjectured by Harary and Plantholt. Β© 1993 John Wiley & Sons, Inc.

Following [1] , we investigate the problem of covering a graph G with induced subgraphs G 1 ; . . . ; G k of possibly smaller chromatic number, but such that for every vertex u of G, the sum of reciprocals of the chromatic numbers of the G i 's containing u is at least 1.

## Abstract It was only recently shown by Shi and Wormald, using the differential equation method to analyze an appropriate algorithm, that a random 5‐regular graph asymptotically almost surely has chromatic number at most 4. Here, we show that the chromatic number of a random 5‐regular graph is as
