Packing perfect matchings in random hypergraphs

Abstract

We introduce a new procedure for generating the binomial random graph/hypergraph models, referred to as \emph{online sprinkling}. As an illustrative application of this method, we show that for any fixed integer k3k\geq 3, the binomial kk-uniform random hypergraph Hn,pkH^{k}_{n,p} contains N:=(1o(1))(n1k1)pN:=(1-o(1))\binom{n-1}{k-1}p edge-disjoint perfect matchings, provided plogCnnk1p\geq \frac{\log^{C}n}{n^{k-1}}, where C:=C(k)C:=C(k) is an integer depending only on kk. Our result for NN is asymptotically best optimal and for pp is optimal up to the polylog(n)polylog(n) factor.
