Abstract

We prove that if $T$ is a tree on $n$ vertices with maximum degree $\Delta$ and the edge probability $p(n)$ satisfies $np\geq C\max\{\Delta\log n,n^{\epsilon}\}$ for some constant $\epsilon0$, then with high probability the random graph $G(n,p)$ contains a copy of $T$. The obtained bound on the edge probability is shown to be essentially tight for $\Delta=n^{\Theta(1)}$.
