我们在$\mathbb{R}^d$上为时间变换布朗运动建立了一个一般的离散逼近方案。该方案适用于$\mathbb{R}^d$上具有完全拟支撑且带有适当初始分布的任意光滑测度。在光滑测度满足某些温和条件时,该离散逼近方案对每个起始点均适用。特别地,我们的结果为刘维尔布朗运动提供了一个离散逼近方案。
英文摘要
We develop a general discrete approximation scheme for time-changed Brownian motions on $\mathbb{R}^d$. Our approximation scheme works for any smooth measure with full quasi-support on $\mathbb{R}^d$ with suitable initial distributions. Under some mild conditions on the smooth measure, the discrete approximation scheme works for every starting point. Our results in particular give a discrete approximation scheme for Liouville Brownian motions.
