Graphs without rainbow triangles
WebJan 30, 2024 · Edge-colorings of complete graphs without rainbow triangles have very interesting and somewhat surprising structure. In 1967, Gallai [14] examined this structure of graphs and it can also be traced back to [6]. For this reason, colored complete graphs without rainbow triangle are called Gallai colorings.

WebJul 5, 2024 · A Gallai coloring of a complete graph G is an edge-coloring of G such that G does not contain a rainbow triangle as a subgraph. This definition is so named in honor of the following classical result, originally by Gallai from 1967. Here a partition of the vertices is called trivial if it partitions the vertex set into only one part.Thus, a nontrivial partition … WebApr 13, 2013 · Abstract Motivated by Ramsey theory and other rainbow-coloring-related problems, we consider edge-colorings of complete graphs without rainbow copy of some fixed subgraphs. Given two graphs G and H, the k-colored Gallai-Ramsey number grk(G : H) is defined to be the minimum positive integer n such that every k-coloring of the …

WebDec 1, 2024 · Abstract. Given an edge-coloring of a hypergraph G, G is said to be rainbow if any two edges of G receive different colors. The anti-Ramsey number A R ( G , H ) of a hypergraph H in a hypergraph G is defined to be the maximum integer k such that there exists a k-edge-coloring of G avoiding rainbow copies of H.The anti-Ramsey numbers of … WebStep 3.
