Decomposition of Cliques into $k$ -Star-Forests

Jiaxi Nie, Yibo Ren, Hehui Wu

A $k$ -star-forest is a forest with at most $k$ connected components where each component is a star. Let $F_{k} (n)$ be the minimum integer such that the complete graph on $n$ vertices…

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…

Evasive sets, twisted varieties, and container-clique trees

Jeck Lim, Jiaxi Nie, Ji Zeng

In the affine space $F_{q}^{n}$ over the finite field of order $q$ , a point set $S$ is said to be $(d, k, r)$ -evasive if the intersection between $S$ and any variety, of dimensi…

Off-Diagonal Ramsey Numbers for Linear Hypergraphs

Xiaoyu He, Jiaxi Nie, Yuval Wigderson +1

We study off-diagonal Ramsey numbers $r (H, K_{n}^{(k)})$ of $k$ -uniform hypergraphs, where $H$ is a fixed linear $k$ -uniform hypergraph and $K_{n}^{(k)}$ is complete on $n$ vertices. R…

Supersaturation of odd linear cycles

Lirong Deng, Jie Han, Jiaxi Nie +1

An $r$ -uniform linear cycle of length $ℓ$ , denoted by $C_{ℓ}^{r}$ , is an $r$ -graph with $ℓ$ edges $e_{1}, e_{2}, \dots, e_{ℓ}$ where $e_i=\{v_{(r-1)(i-1)},v_{(r-1)(i-1)+1},\dots…

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…
