Reflection on rainbow neighbourhood numbers of graphs

WebJan 15, 2024 · A subgraph of G is called rainbow (heterochromatic, or multicolored) if no two edges of it have the same color. For a vertex v of G, we say that color i is presented at vertex v if some edge incident with v has color i. 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. jbhifi apple watch se
