Web26 de mar. de 2024 · The anti-Ramsey number for the short cycle C_3 has been determined in a few graphs. Its anti-Ramsey number in the complete graph can be easily obtained from the lexical edge-coloring. Gorgol considered the problem in complete split graphs which contains complete graphs as a subclass. WebThe anti-Ramsey number of a graph G in a complete graph Kn, denoted by ar(Kn, G), is the maximum number of colors in an edge-coloring of Kn with no rainbow subgraph copy of G. In this paper, we determine the exact value of the anti-Ramsey number for star forests and the approximate value of the anti-Ramsey number for linear forests.
