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

## Abstract This article studies the circular chromatic number of a class of circular partitionable graphs. We prove that an infinite family of circular partitionable graphs __G__ has $\chi\_ c (G) = \chi(G)$. A consequence of this result is that we obtain an infinite family of graphs __G__ with th
Let G be a planar graph. The vertex face total chromatic number ,y13(G) of G is the least number of colors assigned to V(G) U F(G) such that no adjacent or incident elements receive the same color. The main results of this paper are as follows: (1) We give the vertex face total chromatic number for
## Abstract For a vertex __v__ of a graph __G__, we denote by __d__(__v__) the __degree__ of __v__. The __local connectivity__ κ(__u, v__) of two vertices __u__ and __v__ in a graph __G__ is the maximum number of internally disjoint __u__ –__v__ paths in __G__, and the __connectivity__ of __G__ is
## Abstract Let λ(__G__) be the line‐distinguishing chromatic number and __x__′(__G__) the chromatic index of a graph __G__. We prove the relation λ(__G__) ≥ __x__′(__G__), conjectured by Harary and Plantholt. © 1993 John Wiley & Sons, Inc.
