证明了任意n阶k-一致超图,其最小度至少为n2(k−1)+o(n),都包含一个松弛汉密尔顿圈.证明策略与Kühn和Osthus在3-一致情况下使用的策略相似。虽然在k一致的情况下会出现一些额外的困难,但我们的论证通过应用Keevash最近的超图爆破引理而大大简化。
We prove that any k-uniform hypergraph on n vertices with minimum degree at least n2(k−1)+o(n) contains a loose Hamilton cycle. The proof strategy is similar to that used by Kühn and Osthus for the 3-uniform case. Though some additional difficulties arise in the k-uniform case, our argument here is considerably simplified by applying the recent hypergraph blow-up lemma of Keevash.
