随机竞赛图中的单色树

Monochromatic trees in random tournaments

Matija Bucic, Sven Heberle, Shoham Letzter, Benny Sudakov

摘要:

我们证明,以高概率,在每一个$2$ -边着色的随机锦标赛上$n$顶点有一个单色的副本,每一个定向树的顺序$O (n / \sqrt{\log n})$。这概括了第一,第三和第四作者谁证明了同样的声明路径,是紧到一个常数因子。

英文摘要:

We prove that, with high probability, in every $2$-edge-colouring of the random tournament on $n$ vertices there is a monochromatic copy of every oriented tree of order $O (n / \sqrt{\log n})$. This generalises a result of the first, third and forth authors who proved the same statement for paths, and is tight up to a constant factor.
