Edge-disjoint Hamilton cycles in random graphs

preprint2013arXivOpen access

Abstract

We show that provided log⁡50n/n≤p≤1−n−1/4log⁡9n\log^{50} n/n \leq p \leq 1 - n^{-1/4}\log^9 n we can with high probability find a collection of ⌊δ(G)/2⌋\lfloor δ(G)/2 \rfloor edge-disjoint Hamilton cycles in G∼Gn,pG \sim G_{n, p}, plus an additional edge-disjoint matching of size ⌊n/2⌋\lfloor n/2 \rfloor if δ(G)δ(G) is odd. This confirms, for the above range of pp, a conjecture of Frieze and Krivelevich.
