小噪声随机反应扩散方程系统满足对所有初始数据一致的大偏差原理

Systems of small-noise stochastic reaction-diffusion equations satisfy a large deviations principle that is uniform over all initial data

Michael Salins

摘要:

大偏差原理描述了稀有事件概率的指数衰减率。Cerrai和Rockner [13]证明了随机反应扩散方程系统满足在有界初始数据集上一致的大偏差原理。本文证明了一类随机反应扩散方程的一致大偏差结果。此外,本文确定了两种常见的情况下,大偏差原则是一致的,在无界的初始数据集,使Freidlin-Wentzell退出时间和退出形状渐近的特性从无界集。

英文摘要:

Large deviations principles characterize the exponential decay rates of the probabilities of rare events. Cerrai and Rockner [13] proved that systems of stochastic reaction-diffusion equations satisfy a large deviations principle that is uniform over bounded sets of initial data. This paper proves uniform large deviations results for a system of stochastic reaction--diffusion equations in a more general setting than Cerrai and Rockner. Furthermore, this paper identifies two common situations where the large deviations principle is uniform over unbounded sets of initial data, enabling the characterization of Freidlin-Wentzell exit time and exit shape asymptotics from unbounded sets.
