Constrained Ramsey numbers for rainbow $P_{5}$

Xihe Li, Xiangxiang Liu

For any graph $H$ , let $R_{k} (H)$ denote the minimum integer $n$ such that in every $k$ -edge-coloring of $K_{n}$ , there is a monochromatic copy of $H$ . Given two graphs $H$ and $G$ ,…

Edge-colored 3-uniform hypergraphs without rainbow paths of length 3 and applications to Ramsey theory

Xihe Li, Runshan Wang

Motivated by problems in Ramsey theory, we study edge-colorings of 3-uniform hypergraphs that contain no rainbow paths of length 3. We consider the following three natural 3-unifor…
