Résumé :
The 2-distance coloring of a graph G is a proper coloring of G where every pair of vertices sharing a common neighbor
receives different colors.

The "maximum average degree" or "mad" of a graph is the maximum among the average degrees of its subgraphs.
This is a way to evaluate the density (or the sparseness) of a graph, both globally and locally.

Several results exist about the lesser number of colors needed for 2-distance coloring of graphs with bounded mad.
However, in all these results, the bound is strictly lesser than 4.

We present upper and lower bounds for the "2-distance chromatic number" of graphs with mad bounded by 2k for every k.
