Abstract

The current article is devoted to the study of a mean-field system of particles. The question that we are interested in is the behaviour of the exit-time of the first particle (and the one of any particle) from a domain D on ℝd as the diffusion coefficient goes to 0. We establish a Kramers’ type law. In other words, we show that the exit-time is exponentially equivalent to [see formula in PDF], HN being the exit-cost. We also show that this exit-cost converges to some quantity H.

平均场粒子系统的退出时间
本文致力于研究粒子的平均场系统。我们感兴趣的问题是,当扩散系数趋于0时,第一个粒子(以及任意一个粒子)在域D上的存在时间的行为。我们建立了克莱默类型定律。换句话说,我们证明退出时间是指数等价的[见PDF中的公式],HN是退出成本。我们也证明了这个退出成本收敛于某个量H。
