Multicolor Ramsey numbers of ordered matchings

Xiangyu Li

For an ordered graph $H$ and an integer $q \geq 2$ , let $r_{<} (H; q)$ denote the $q$ -color ordered Ramsey number of $H$ . Conlon, Fox, Lee and Sudakov asked whether, for every $q \ge…

Multicolor $K_{r}$ -Tilings with High Discrepancy

Henry Chan, Daniel Cheng, Lior Gishboliner +1

We study the minimum degree threshold $δ_{r, q}$ guaranteeing the existence of $K_{r}$ -tilings of high discrepancy in any $q$ -edge-coloring. Balogh, Csaba, Pluhár and Treglown handled…
