Title
Tura´n's extremal problem in random graphs: forbidding even cycles
Abstract
For 0 < γ ≤ 1 and graphs G and H , we write G [formula] H if any γ-proportion of the edges of G span at least one copy of H in G . As customary, we write C k for a cycle of length k . We show that, for every fixed integer l ≥ 2 and real γ > 0, there exists constant C = C ( l , γ) > 0 such that almost every random graph G n, p with p = p ( n ) ≥ Cn −1 + 1/(2 l − 1) satisfies G n,p [formula] C 2 l . In particular, for any fixed l ≥ 2 and γ > 0, this result implies the existence of very sparse graphs G with G [formula] C 2 l .
