离散点过程上简单随机游动的猝灭不变原理

Quenched invariance principle for simple random walk on discrete point processes

Naoki Kubota

摘要:

本文考虑离散点过程生成的随机图上的简单随机游动。该随机图具有立方晶格的随机子集作为顶点,并且平行于每个坐标轴的线上的任何连续顶点之间的线作为边。在离散点过程是平稳的、依赖于时间的假设下,我们证明了猝灭不变原理成立,即对几乎每一个点过程的构形,其游动的路径分布都弱收敛于布朗运动的路径分布.

英文摘要:

We consider the simple random walk on random graphs generated by discrete point processes. This random graph has a random subset of a cubic lattice as the vertices and lines between any consecutive vertices on lines parallel to each coordinate axis as the edges. Under the assumption that discrete point processes are finitely dependent and stationary, we prove that the quenched invariance principle holds, that is, for almost every configuration of a point process, the path distribution of the walk converges weakly to that of a Brownian motion.
