论文摘要
我们给出了骨骼引理的新证明，这是我们有关汉密尔顿周期的论文中的主要技术工具[T. T. Kaiser和P.Vrána，汉密尔顿循环中的5个连接线图，欧洲J. Combin。 33（2012），924-947]。它将结果概括为在图中跨越树的脱节到3个hypergraphs的上下文。引理以稍强的版本证明，更适合应用。简化证明并以更易于访问的方式制定。
We give a new proof of the Skeletal Lemma, which is the main technical tool in our paper on Hamilton cycles in line graphs [T. Kaiser and P. Vrána, Hamilton cycles in 5-connected line graphs, European J. Combin. 33 (2012), 924-947]. It generalises results on disjoint spanning trees in graphs to the context of 3-hypergraphs. The lemma is proved in a slightly stronger version that is more suitable for applications. The proof is simplified and formulated in a more accessible way.
