Abstract
Let be a sufficiently large integer with and let where . We show that if each vertex of is contained in more than edges, then admits a rainbow matching, i.e., a set of edges consisting of one edge from each . This generalizes a deep result of Khan on perfect matchings in 4-uniform hypergraphs.
