离散交错和离散交错上的随机游动

Random Walks on Discrete Cylinders and Random Interlacements

Alain-Sol Sznitman

摘要:

我们探索了离散圆柱体上简单随机游动轨迹留下的局部图像之间的一些联系,该离散圆柱体以d维环面为底,d至少为2,边长为N,运行次数为N^{2d}阶,arXiv:0704.2560中最近引入的随机交错模型。特别是,我们表明,当基地变得很大,在附近的一个点的圆柱与一个垂直分量的顺序N^d,补充的一组点访问的时间顺序N^{2d},是接近的分布规律的空集的随机交错在一个水平,这是由一个独立的布朗当地时间。本文还导出了局部图像在多点邻域内的极限。

英文摘要:

We explore some of the connections between the local picture left by the trace of simple random walk on a discrete cylinder with base a d-dimensional torus, d at least 2, of side-length N running for times of order N^{2d} and the model of random interlacements recently introduced in arXiv:0704.2560. In particular we show that when the base becomes large, in the neighborhood of a point of the cylinder with a vertical component of order N^d, the complement of the set of points visited by the walk up to times of order N^{2d}, is close in distribution to the law of the vacant set of random interlacements at a level which is determined by an independent Brownian local time. The limit of the local pictures in the neighborhood of finitely many points is also derived.
