关于小强度无规交织有限空簇的大小

On the size of a finite vacant cluster of random interlacements with small intensity

Augusto Teixeira

摘要:

本文建立了随机交错的空集的渗流的一些性质,其中d至少为5,且强度u较小。随机交织模型是由A.S. Sznitman in arXiv:0704.2560.众所周知,对于小u,几乎可以肯定的是,在由水平u处的随机交错留下的空集合中存在唯一的无限连通分量,参见arXiv:0808.3344和arXiv:0805.4106。我们在这里估计的直径分布和体积的空组件在水平u包含原点,鉴于它是有限的。这是我们的主要定理的副产品,它证明了一个扩展的指数界的概率,交错集分离两个宏观连通集在一个大的立方体。作为另一个应用程序,我们表明,具有很高的概率,唯一的无限连通组件的空集是“无处不在”的大邻域的起源。

英文摘要:

In this paper we establish some properties of percolation for the vacant set of random interlacements, for d at least 5 and small intensity u. The model of random interlacements was first introduced by A.S. Sznitman in arXiv:0704.2560. It is known that, for small u, almost surely there is a unique infinite connected component in the vacant set left by the random interlacements at level u, see arXiv:0808.3344 and arXiv:0805.4106. We estimate here the distribution of the diameter and the volume of the vacant component at level u containing the origin, given that it is finite. This comes as a by-product of our main theorem, which proves a stretched exponential bound on the probability that the interlacement set separates two macroscopic connected sets in a large cube. As another application, we show that with high probability, the unique infinite connected component of the vacant set is `ubiquitous' in large neighborhoods of the origin.
