WebApr 25, 2024 · Normal edge-colorings of cubic graphs. Giuseppe Mazzuoccolo, Vahan Mkrtchyan. A normal -edge-coloring of a cubic graph is an edge-coloring with colors having the additional property that when looking at the set of colors assigned to any edge and the four edges adjacent it, we have either exactly five distinct colors or exactly three … WebUsing graph-theoretic language, the nite version of Ramsey’s theorem can be stated in the following way. Theorem A. (Ramsey [18]). Let s;t 2. Then, there exists a minimal positive integer n such that every edge coloring of K. n (using two colors) contains a monochromatic K. s. or a monochromatic K. t. Considerable work has been done 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. WebA k-edge-coloring is a partition of the edges of a graph into k(color) classes so that no adjacent edges are in the same class. Notice that we do not label the color classes in …
WebApr 30, 2024 · Local edge colorings of graphs. Definition 1.4. For k ≥ 2, a k-local edge coloring of a graph G of edge size at least 2 is a function c: E ( G) → N having the property that for each set S ⊆ E ( G) with 2 ≤ S ≤ k, there exist edges e 1, e 2 ∈ S such that c ( e 1) − c ( e 2) ≥ n s, where ns is the number of copies of P3 in ... WebJan 15, 2024 · An edge-colored graph is called rainbow if all the edges have the different colors. The anti-Ramsey number AR(G, H) of a graph H in the graph G is defined to be the maximum number of colors in an edge-coloring of G which does not contain any rainbow H. In this paper, the existence of rainbow triangles in edge-colored Kneser graphs is studied.
