Supersaturation beyond color-critical graphs

Jie Ma, Long-Tu Yuan

The supersaturation problem for a given graph $F$ asks for the minimum number $h_{F} (n, q)$ of copies of $F$ in an $n$ -vertex graph with $e x (n, F) + q$ edges. Subsequent works by Rademac…

Exact results for some extremal problems on expansions I

Xizhi Liu, Jialei Song, Long-Tu Yuan

The expansion of a graph $F$ , denoted by $F^{3}$ , is the $3$ -graph obtained from $F$ by adding a new vertex to each edge such that different edges receive different vertices. For lar…

A step towards a general density Corrádi--Hajnal Theorem

Jianfeng Hou, Heng Li, Xizhi Liu +2

For a nondegenerate $r$ -graph $F$ , large $n$ , and $t$ in the regime $[0, c_{F} n]$ , where $c_{F} > 0$ is a constant depending only on $F$ , we present a general approach for determining…
