Almost-spanning universality in random graphs

Abstract

A graph GG is said to be H(n,Δ)\mathcal H(n,\Delta)-universal if it contains every graph on nn vertices with maximum degree at most Δ\Delta. It is known that for any ε>0\varepsilon > 0 and any natural number Δ\Delta there exists c>0c > 0 such that the random graph G(n,p)G(n,p) is asymptotically almost surely H((1ε)n,Δ)\mathcal H((1-\varepsilon)n,\Delta)-universal for pc(logn/n)1/Δp \geq c (\log n/n)^{1/\Delta}. Bypassing this natural boundary, we show that for Δ3\Delta \geq 3 the same conclusion holds when p=ω(n1Δ1log5n)p = \omega\left(n^{-\frac{1}{\Delta-1}}\log^5 n\right).
