带上随机环境中随机游动的大偏差

Large deviations for random walks in a random environment on a strip

Jonathon Peterson

摘要:

考虑有限宽带$\mathbb{Z} \times \{1,2,\ldots,d\}$上随机环境中的随机游动.我们证明淬火和平均大偏差原则的位置和首中时的RWRE。此外,我们证明了一个变分公式,它将猝灭和平均速率函数联系起来,从而推广了Comets,Gantert和Zeitouni关于$\mathbb{Z}$上最近邻RWRE的结果

英文摘要:

We consider a random walk in a random environment (RWRE) on the strip of finite width $\mathbb{Z} \times \{1,2,\ldots,d\}$. We prove both quenched and averaged large deviation principles for the position and the hitting times of the RWRE. Moreover, we prove a variational formula that relates the quenched and averaged rate functions, thus extending a result of Comets, Gantert, and Zeitouni for nearest-neighbor RWRE on $\mathbb{Z}$
