随机环境中带上的瞬态随机游动

Transient random walks on a strip in a random environment

Alexander Roitershtein

摘要:

考虑随机环境中带状上的瞬态随机游动。该模型由Bolthausen和Goldsheid提出[Comm.Math.Phys.214(2000)429- 447]。在一般遍历环境下,我们得到了随机游动的一个强大数律,并在一致混合环境下得到了一个退火的中心极限定理。此外,我们证明了法律的“环境从步行者的位置来看”收敛到一个极限分布,如果环境是一个独立同分布。顺序

英文摘要:

We consider transient random walks on a strip in a random environment. The model was introduced by Bolthausen and Goldsheid [Comm. Math. Phys. 214 (2000) 429--447]. We derive a strong law of large numbers for the random walks in a general ergodic setup and obtain an annealed central limit theorem in the case of uniformly mixing environments. In addition, we prove that the law of the "environment viewed from the position of the walker" converges to a limiting distribution if the environment is an i.i.d. sequence.
