Lagrangian densities of hypergraph cycles

Yuejian Peng, Zilong Yan

The Lagrangian density of an $r$ -uniform hypergraph $F$ is $r!$ multiplying the supremum of the Lagrangians of all $F$ -free $r$ -uniform hypergraphs. For an $r$ -graph $H$ with $t$ v…

3-colored asymmetric bipartite Ramsey number of connected matchings and cycles

Zhidan Luo, Yuejian Peng

Let $k, l, m$ be integers and $r (k, l, m)$ be the minimum integer $N$ such that for any red-blue-green coloring of $K_{N, N}$ , there is a red matching of size at least $k$ in a componen…

Bipartite Ramsey numbers of large cycles

Shaoqiang Liu, Yuejian Peng

For an integer $r \geq 2$ and bipartite graphs $H_{i}$ , where $1 \leq i \leq r$ , the bipartite Ramsey number $b r (H_{1}, H_{2}, \dots, H_{r})$ is the minimum integer $N$ such that any $r$ -edge c…

On Lagrangians of $3$ -uniform hypergraphs

Hui Lei, Linyuan Lu, Yuejian Peng

Frankl and Füredi conjectured in 1989 that the maximum Lagrangian of all $r$ -uniform hypergraphs of fixed size $m$ is realized by the minimum hypergraph $C_{r, m}$ under the colexic…
