摘要

利用Dirichlet外问题与漂移布朗运动之间存在的密切联系,对Dirichlet外问题提出了一种新的有效的概率数值方法,这种方法运用了解的随机表达式、布朗运动、漂移布朗运动以及球面首中位置和时间的分布等.

Abstract

In this paper, by using the deep connections between the Brownian motion with drift and the exterior Dirichlet problem, a new efficient probabilistic numerical method is proposed. The method is based on the stochastic representations of
solutions, Brownian motion, Brownian motion with drift and the distribution of the time and place of hitting spheres from outside the sphere.
