双随机环境中随机游动的中心极限定理和常返性

Central Limit Theorem and recurrence for random walks in bistochastic random environments

Marco Lenci

摘要:

证明了局部漂移为零的$Z^d$上双随机环境中随机游动的退火中心极限定理.这个证明是基于对系统的“动力学解释”,并且需要一个比习惯的一致椭圆性弱得多的条件。此外,推导了$d \le 2$的递推公式。

英文摘要:

We prove the annealed Central Limit Theorem for random walks in bistochastic random environments on $Z^d$ with zero local drift. The proof is based on a "dynamicist's interpretation" of the system, and requires a much weaker condition than the customary uniform ellipticity. Moreover, recurrence is derived for $d \le 2$.
