亚临界连续渗流无界空集的存在性

Existence of an unbounded vacant set for subcritical continuum percolation

Daniel Ahlberg, Vincent Tassion, Augusto Teixeira

摘要:

我们考虑了$\mathbb{R}^2$中的Poisson布尔渗流模型,其中每个球的半径根据有限二阶矩的概率测度独立选择.对于这个模型,我们表明,两个阈值,存在一个无界的占用和一个无界的空置组件,重合。这补充了最近的一项研究的尖锐性的相变在泊松布尔渗流由相同的作者。作为一个推论,它遵循的泊松布尔渗流在$\mathbb{R}^d$,对任何$d\ge2$,有限矩的顺序$d$是必要的和充分的存在一个非平凡的相变的空集。

英文摘要:

We consider the Poisson Boolean percolation model in $\mathbb{R}^2$, where the radii of each ball is independently chosen according to some probability measure with finite second moment. For this model, we show that the two thresholds, for the existence of an unbounded occupied and an unbounded vacant component, coincide. This complements a recent study of the sharpness of the phase transition in Poisson Boolean percolation by the same authors. As a corollary it follows that for Poisson Boolean percolation in $\mathbb{R}^d$, for any $d\ge2$, finite moment of order $d$ is both necessary and sufficient for the existence of a nontrivial phase transition for the vacant set.
