Every Steiner triple system contains an almost spanning d-ary hypertree

Abstract

In this paper we make a partial progress on the following conjecture: for every $\mu >0$ and large enough $n$, every Steiner triple system $S$ on at least $(1+\mu )n$ vertices contains every hypertree $T$ on $n$ vertices. We prove that the conjecture holds if $T$ is a perfect $d$-ary hypertree.
