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

We consider vertex colorings in which each color has an associated cost, incurred each time the color is assigned to a vertex. For a given set of costs, a minimum-cost coloring is a vertex coloring which makes the total cost of coloring the graph as small as possible. The cost-chromatic number of a

## Abstract Jeager et al. introduced a concept of group connectivity as a generalization of nowhere zero flows and its dual concept group coloring, and conjectured that every 5‐edge connected graph is Z~3~‐connected. For planar graphs, this is equivalent to that every planar graph with girth at lea
