正则竞赛图的Hamilton分解

Hamilton decompositions of regular tournaments

Daniela Kühn, Deryk Osthus, Andrew Treglown

摘要:

我们证明了每一个足够大的正则竞赛图几乎可以完全分解为边不相交的Hamilton圈。更精确地说,对于每个η>0,每个足够大阶的正则竞赛图G至少包含(1/2-η)n个边不相交的Hamilton圈。这给出了一个近似解的猜想凯利从1968年。我们的结果也延伸到几乎定期的比赛。

英文摘要:

We show that every sufficiently large regular tournament can almost completely be decomposed into edge-disjoint Hamilton cycles. More precisely, for each η>0 every regular tournament G of sufficiently large order n contains at least (1/2-η)n edge-disjoint Hamilton cycles. This gives an approximate solution to a conjecture of Kelly from 1968. Our result also extends to almost regular tournaments.
