随机势场中布朗运动的猝灭大偏差

Quenched large deviations for brownian motion in a random potential

Daniel Boivin, Thi Thu Hien Lê

摘要:

证明了非负定常势场中布朗运动的猝灭大偏差原理。给出了势的充分矩条件,但与Armstrong和Tran(2014)的结果不同,没有假设正则性。证明是基于Sznitman(1994)对Poissonian势中的布朗运动提出的一种方法。特别地,LDP适用于多项式衰减相关的势,如L。Pastur(1977)和R. Fukushima(2008)和H. Lacoin(2012).

英文摘要:

A quenched large deviation principle for Brownian motion in a non-negative, stationary potential is proved. A sufficient moment condition on the potential is given but unlike the results of Armstrong and Tran (2014) no regularity is assumed. The proof is based on a method developed by Sznitman (1994) for Brownian motion among Poissonian potential. In particular, the LDP holds for potentials with polynomially decaying correlations such as the classical potentials studied by L. Pastur (1977) and R. Fukushima (2008) and the potentials recently introduced by H. Lacoin (2012).
