在无限渗透的基础上,通过一个行进路线访问点的名称

Sur le nombre de points visités par une marche aléatoire sur un amas infini de percolation

Clement Rau

摘要:

本文研究了$\Z^d (d \geq 2)$上无限团簇的键渗流问题。我们表明,访问点数量的拉普拉斯变换$N\_n$具有与随机游动在$\Z^d$上相同的行为。更确切地说,对于所有的$0<α<1$,我们证明了存在常数$C\_i$和$C\_s$,使得对于所有包含原点的无限簇,我们有:$$ e^{-C\_i n^{\frac{d}{d+2}}} \leq \E\_0^ω (α^{N\_n}) \leq e^{-C\_sn^{\frac{d}{d+2}}}.$$我们的方法是基于找到一个等周不等式上的无限簇,解除了圈积,使良好的行为。关于圈积的等周问题,早在1989年由A.Ershler提出。

英文摘要:

In this article, we consider random walk on the infinite cluster of bond percolation on $\Z^d (d \geq 2)$. We show that the Laplace transformation of the number of visited points $N\_n$, has a behaviour as the random walk was on $\Z^d$. More precisely, for all $0<α<1$, we proved that there exist constants $C\_i$ and $C\_s$ such that for all infinite cluster that contains the origin, we have: $$ e^{-C\_i n^{\frac{d}{d+2}}} \leq \E\_0^ω (α^{N\_n}) \leq e^{-C\_sn^{\frac{d}{d+2}}}.$$ Our approach is based on finding an isoperimetric inequalities on the infinite cluster, lifted on a wreath product which give good behaviour. The problem of the isoperimetry on wreath product was already raised by A.Ershler.
