在2010年,Lichiardopol证明了对于$q geqslane 3$和$k geqslane 1$,任何最小出度至少为$(q-1)k-1$的竞赛图都包含$k$个长度为$q$的不相交圈。以前的猜想是已知的成立为$qleqslant 4$。我们证明它对$q geqslant 5$成立,从而完成了猜想的证明。
In 2010, Lichiardopol conjectured for $q geqslant 3$ and $k geqslant 1$ that any tournament with minimum out-degree at least $(q-1)k-1$ contains $k$ disjoint cycles of length $q$. Previously the conjecture was known to hold for $qleqslant 4$. We prove that it holds for $q geqslant 5$, thereby completing the proof of the conjecture.
