A brief structured survey on the problems and their applications in … WebGiven a positive integer k, an edge-coloring of G is called a k-rainbow connection coloring if for every set S of k vertices of G, there exists one rainbow S-tree in G. Every connected graph G has a trivial k-rainbow connection coloring: choose a spanning tree T of G and just color each edge of T with a distinct color.

WebLet us mention that the notion of nonrepetitive coloring of graphs, as introduced by Alon, Hałuszczak, Grytczuk, and Riordan in [1], can be considered more generally, in a way similar to the usual proper coloring of graphs (in both, edge or vertex version). A recent survey by Wood [22] collects many interesting results on this topic.
