The generalized coloring numbers colr(G) (also denoted by scolr(G)) and wcolr(G) of a graph G were introduced by Kierstead and Yang as a generalization of the usual coloring number, and have found important theoretical and algorithmic applications. For each distance r, these numbers are determined by an “optimal” ordering of the vertices of G. We study the question of whether it is possible to find a single “uniform” ordering that is “good” for all distances r. We show that the answer to this question is essentially “yes”. Our results give new characterizations of graph classes with bounded expansion and nowhere dense graph classes.
