The List-Chromatic Number of Infinite Graphs Defined on Euclidean Spaces


If D is a countable set of positive reals, 2 ≤ n < ω, let Xn(D) be the graph with the points of R as vertices where two vertices are joined iff their distance is in D. We determine the list-chromatic number of Xn(D) as much as possible.
