1999年,Benjamini、Lyons、Peres和Schramm的两篇论文表明,对于单模非可和准传递图上的伯努利渗流,在临界值处不存在无限簇。我们利用可数Borel等价关系理论和Gaboriau的簇图构造,给出了该结果的简短证明。我们还指出了簇图构造在文献中的其他用途,例如在arXiv:1509.00247 [math.GR]中用于证明p_u处的非唯一性。本简短说明的目的是让专家熟知的民间证明能被概率学家和测度群论学家的更广泛群体所理解。
英文摘要
In 1999, two papers of Benjamini, Lyons, Peres, and Schramm showed that for Bernoulli percolation on unimodular nonamenable quasi-transitive graphs, there are no infinite clusters at criticality. Using the theory of countable Borel equivalence relations and Gaboriau's cluster graphing construction, we give a short proof of this result. We also point out other uses of the cluster graphing construction in the literature, for instance in showing nonuniqueness at $p_u$ in arXiv:1509.00247 [math.GR]. The purpose of this short note is to make folklore proofs known to experts more accessible to the wider community of probabilists and measured group theorists.
