Maximum in-general-position set in a random subset of $F_{q}^{d}$

Yaobin Chen, Jiaxi Nie, Jing Yu +1

Let $α (F_{q}^{d}, p)$ be the maximum possible size of a point set in general position in a $p$ -random subset of $F_{q}^{d}$ . We determine the order of magnitude of $α(\m…

Generalized Erdős-Rogers problems for hypergraphs

Xiaoyu He, Jiaxi Nie

Given $r$ -uniform hypergraphs $G$ and $F$ and an integer $n$ , let $f_{F, G} (n)$ be the maximum $m$ such that every $n$ -vertex $G$ -free $r$ -graph has an $F$ -free induced subgraph on…

Random Turán Problems for $K_{s, t}$ Expansions

Jiaxi Nie, Sam Spiro

Let $K_{s, t}^{(r)}$ denote the $r$ -uniform hypergraph obtained from the graph $K_{s, t}$ by inserting $r - 2$ new vertices inside each edge of $K_{s, t}$ . We prove essentially tight bo…
