论文摘要
在这篇非常简短的论文中，我们指出，$ \ {1,2，\ ldots，n \} $的子集的平均重叠密度的平均重叠密度可能小如$θ（（\ log log \ log \ log \ log \ f}整数$ n $。
In this very short paper, we point out that the average overlap density of a union-closed family $\mathcal{F}$ of subsets of $\{1,2,\ldots,n\}$ may be as small as $Θ((\log \log |\mathcal{F}|)/(\log |\mathcal{F}|))$, for infinitely many positive integers $n$.
