该研究针对二维带反射边界且含小型出射窗口的区域,采用谱方法,在出射窗口无限小的极限下,从拟平稳分布出发,精确描述了布朗运动的出射事件规律。
AI 中文摘要
我们研究带有反射边界条件的二维区域中布朗运动的首达时间与出射点规律,仅在互不相交的小型出射窗口处,该随机过程可逃逸出区域。在出射窗口无限小的极限下,自然假设过程从拟平稳分布出发,在此设定下,我们对出射事件给出了精确描述。
英文摘要
We study the law of the exit time and exit point of a Brownian motion in a two-dimensional domain with reflecting boundary conditions, except on small disjoint exit windows through which the stochastic process can escape the domain. In the limit of infinitely small exit windows, it is natural to assume that the process starts from the quasi-stationary distribution. In this setting, we obtain a precise description of the exit event.
