We study the following question raised by Erdős and Hajnal in the early 90’s. Over all-vertex graphswhat is the smallest possible value offor which anyvertices ofcontain both a clique and an independent set of size? We construct examples showing thatis at mostobtaining a twofold sub-polynomial improvement over the upper bound of aboutcoming from the natural guess, the random graph. Our (probabilistic) construction gives rise to new examples of Ramsey graphs, which while having no very large homogenous subsets contain both cliques and independent sets of sizein any small subset of vertices. This is very far from being true in random graphs. Our proofs are based on an interplay between taking lexicographic products and using randomness. References
