随机环境中多维随机游动的退火大偏差速率函数

On the annealed large deviation rate function for a multi-dimensional random walk in random environment

Jonathon Peterson, Ofer Zeitouni

摘要:

本文导出了随机环境中多维弹道式随机游动的Varadhan(退火)大偏差原理中速率函数在零集的某个邻域内的性质.我们的方法将LDP与再生时间和距离联系起来。由于i.i.d.,后者的分析是可能的。再生结构。

英文摘要:

We derive properties of the rate function in Varadhan's (annealed) large deviation principle for multidimensional, ballistic random walk in random environment, in a certain neighborhood of the zero set of the rate function. Our approach relates the LDP to that of regeneration times and distances. The analysis of the latter is possible due to the i.i.d. structure of regenerations.
