随机图中的偏色Hamilton圈

Colour-biased Hamilton cycles in random graphs

Lior Gishboliner, Michael Krivelevich, Peleg Michaeli

摘要:

我们证明了一个随机图$G(n,p)$,$p$以上的哈密尔顿性阈值,通常是这样的,任何$r$着色的边缘存在哈密尔顿循环至少$(2/(r+ 1)-o(1))n$边缘相同的颜色。这个估计是渐近最优的。

英文摘要:

We prove that a random graph $G(n,p)$, with $p$ above the Hamiltonicity threshold, is typically such that for any $r$-colouring of its edges there exists a Hamilton cycle with at least $(2/(r+ 1)-o(1))n$ edges of the same colour. This estimate is asymptotically optimal.
