The typical structure of graphs with no large cliques

Abstract

In 1987, Kolaitis, Pr\"omel and Rothschild proved that, for every fixed rNr \in \mathbb{N}, almost every nn-vertex Kr+1K_{r+1}-free graph is rr-partite. In this paper we extend this result to all functions r=r(n)r = r(n) with r(logn)1/4r \leqslant (\log n)^{1/4}. The proof combines a new (close to sharp) supersaturation version of the Erd\H{o}s-Simonovits stability theorem, the hypergraph container method, and a counting technique developed by Balogh, Bollob\'as and Simonovits.
