Coloring triangles in graphs

Combinatorics 2024-11-21 v1

Abstract

We study quantitative aspects of the following fact: For every graph FF, there exists a graph GG with the property that any 22-coloring of the triangles of GG yields an induced copy of FF, in which all triangles are monochromatic. We define the Ramsey number RindΔ(F)R_{\text{ind}}^{\Delta}(F) as the smallest size of such a graph GG. Although this fact has several proofs, all of them provide tower-type bounds. We study the number RindΔ(F)R_{\text{ind}}^{\Delta}(F) for some particular classes of graphs FF.
