Abstract. We revisit the Kahn–Kalai conjecture, recently proved in striking fashion by Park and Pham, and present a slightly reformulated simple proof which has a few advantages: (1) it works for nonuniform product measures, (2) it gives near-optimal bounds even for sampling probabilities close to 1, (3) it gives a clean bound of [math] for every [math]-bounded set system, [math].

非均匀卡恩-卡莱猜想的简单证明
SIAM 离散数学杂志》,第 38 卷第 3 期,第 2089-2094 页,2024 年 9 月。 摘要。我们重温了最近由 Park 和 Pham 以惊人的方式证明的 Kahn-Kalai 猜想,并提出了一个略微重新表述的简单证明,它有几个优点:(1) 它适用于非均匀积度量;(2) 即使在抽样概率接近 1 的情况下,它也给出了接近最优的约束;(3) 它为每一个[math]有界集合系统给出了一个干净的[math]约束[math]。
