On the maximum number of triangles in tripartite graphs with no $4$ -cycles between any two parts

Chunqiu Fang, Rongxing Xu

Let $G$ be a $3$ -partite graph with $k$ vertices in each part such that the bipartite graph induced by any two parts contains no cycle of length four. Fischer and Matoušek [J. Comb…

On local Turán density problems of hypergraphs

Chunqiu Fang, Guorong Gao, Jie Ma +1

For integers $q \geq p \geq r \geq 2$ , we say that an $r$ -uniform hypergraph $H$ has property $(q, p)$ , if for any $q$ -vertex subset $Q$ of $V (H)$ , there exists a $p$ -vertex subset $P$ of…
