关于避免长为4的圈的$3$ -一致超图

On $3$-uniform hypergraphs avoiding a cycle of length four

Beka Ergemlidze, Ervin Győri, Abhishek Methuku, Nika Salia, Casey Tompkins

摘要:

本文证明了不含长度为4的Berge圈的$3$ -一致超图的最大边数至多为$(1+o(1))\frac{n^{3/2}}{\sqrt{10}}$ .这改进了Gyagri和Lemons以及Füredi和Özkahya早先的估计。

英文摘要:

In this note we show that the maximum number of edges in a $3$-uniform hypergraph without a Berge cycle of length four is at most $(1+o(1))\frac{n^{3/2}}{\sqrt{10}}$. This improves earlier estimates by Győri and Lemons and by Füredi and Özkahya.
