长程渗流簇上随机游动的标度极限

Scaling limits for random walks on long range percolation clusters

Noam Berger, Yuki Tokushige

AI总结:

研究整数格上超临界长程渗流簇的简单随机游动,证明其标度极限收敛于各向同性 alpha-稳定 Levy 过程,且收敛在 quenched 和 annealed 意义下均成立。

摘要:

我们研究整数格上超临界长程渗流簇上简单随机游动的极限律。对于长程渗流模型,两个顶点相连的概率渐近表现为它们之间距离的负幂次。我们证明,无穷大连通分量上简单随机游动的标度极限收敛于各向同性的 alpha-稳定 Levy 过程。这补充了 Crawford 和 Sly 的工作,他们证明了 alpha 在 0 和 1 之间时的相应结果。该收敛在 quenched 和 annealed 意义下均成立。

英文摘要:

We study limit laws for simple random walks on supercritical long-range percolation clusters on the integer lattice. For the long range percolation model, the probability that two vertices are connected behaves asymptotically as a negative power of distance between them. We prove that the scaling limit of simple random walk on the infinite component converges to an isotropic alpha-stable Levy process. This complements the work of Crawford and Sly, who proved the corresponding result for alpha between 0 and 1. The convergence holds in both the quenched and annealed senses.
