On the random version of the Erd\H{o}s matching conjecture
Abstract
The Kneser hypergraph is an -uniform hypergraph with vertex set consisting of all -subsets of and any collection of vertices forms an edge if their corresponding -sets are pairwise disjoint. The random Kneser hypergraph is a spanning subhypergraph of in which each edge of is retained independently of each other with probability . The independence number of random subgraphs of was recently addressed in a series of works by Bollob{\'a}s, Narayanan, and Raigorodskii (2016), Balogh, Bollob{\'a}s, and Narayanan (2015), Das and Tran (2016), and Devlin and Kahn (2016). It was proved that the random counterpart of the Erd\H{o}s-Ko-Rado theorem continues to be valid even for very small values of . In this paper, generalizing this result, we will investigate the independence number of random Kneser hypergraphs . Broadly speaking, when is much smaller that , we will prove that the random analogue of the Erd\H{o}s matching conjecture is true even for extremely small values of .
