WebHere the goal is to show that locally-bounded edge-colourings of the complete graph Kn contain rainbow copies of certain graphs. An edge-colouring is locally k-bounded if each ... colouring of Knwith no rainbow Hamilton path. Nevertheless, it is widely believed that any properly coloured Kncontains a rainbow path covering all but exceptionally ... WebSuppose that Gis an edge colored graph with no rainbow copy of ... This construction is not the complete graph when k>3. Theorem 3.1. Let Pk be the path of length k,then ex∗(n,P k)≥ k 2 n+O(1). Proof. Consider the edge-colored graph D∗ 2s. Suppose that P is a rainbow path of

WebFeb 13, 2009 · For an ℓ-connected graph G and an integer k with 1 ≤ k ≤ ℓ, the rainbow k-connectivity rc k (G) of G is the minimum integer j for which there exists a j-edge-coloring … WebJul 1, 2024 · Abstract. Motivated by Ramsey-type questions, we consider edge-colorings of complete graphs and complete bipartite graphs without rainbow path. Given two graphs G and H, the k-colored Gallai–Ramsey number g r k ( G : H ) is defined to be the minimum integer n such that n 2 ≥ k and for every N ≥ n, every rainbow G-free coloring (using all ...
