WebFor two graphs S and T, the constrained Ramsey number f(S, T) is the minimum n such that every edge colouring of the complete graph on n vertices (with any number of colours) has a monochromatic subgraph isomorphic to S or a rainbow subgraph isomorphic to T. Here, a subgraph is said to be rainbow if all of its edges have different colours. WebIt is shown that, for every edge-colouring of the complete graph on n vertices, there is either a monochromatic copy of S or a rainbow copy of P, and the number of vertices needed grows only linearly in t.
