报告摘要:Kuhn, Osthus and Treglown (and, independently, of Khan) gave the tight degree condition for the existence of perfect matching in 3-graphs. We give tight sufficient conditions for the existence of near perfect matching in term (k-2)-degree. If k=3, our result implies that above result. In this talk, we will introduce our new proof on perfect matching in 3-graphs. Our method is new and it can be used to study the other matching problems of hypergraphs.
