直线上随机游动的常返率和首中时分布

Recurrence rates and hitting-time distributions for random walks on the line

Francoise Pene, Benoît Saussol, Roland Zweimüller

摘要:

我们考虑由一系列独立同分布的跳跃构成的直线上的随机游动,这些跳跃属于稳定分布的严格吸引区域,并且首先确定当r趋于零时返回时间to(-r,r)的几乎必然指数发散率。然后,我们通过建立任意实数x的(x-r,x+r)的首中时分布的极限定理来改进这个结果。

英文摘要:

We consider random walks on the line given by a sequence of independent identically distributed jumps belonging to the strict domain of attraction of a stable distribution, and first determine the almost sure exponential divergence rate, as r goes to zero, of the return time to (-r,r). We then refine this result by establishing a limit theorem for the hitting-time distributions of (x-r,x+r) with arbitrary real x.
