New bounds of two hypergraph Ramsey problems

Chunchao Fan, Xinyu Hu, Qizhong Lin +1

We focus on two hypergraph Ramsey problems. First, we consider the Erdős-Hajnal function $r_{k} (k + 1, t; n)$ . In 1972, Erdős and Hajnal conjectured that the tower growth rate of $r_k(k+…

A step towards the Ramsey-Turán conjecture for $K_{3}$ and $K_{6}$

Xinyu Hu, Qizhong Lin

Ramsey-Turán type problems were initiated by Erdős and Sós in 1969. Given integers $p, q \geq 2$ , a graph $G$ is $(K_{p}, K_{q})$ -free if there exists a red/blue edge coloring of $G$ such…
