英文摘要:
This paper proposes and analyses a new multilevel Monte Carlo method for the estimation of mean exit times for multi-dimensional Brownian diffusions, and associated functionals which correspond to solutions to high-dimensional parabolic PDEs through the Feynman-Kac formula. In particular, it is proved that the complexity to achieve an $\\varepsilon$ root-mean-square error is $O(\\varepsilon^{-2}\\, |\\!\\log \\varepsilon|^3)$.

中文摘要:
本文提出并分析了一种新的多层蒙特卡罗方法,用于估计多维布朗扩散的平均退出时间,以及通过费曼-卡克公式对应于高维抛物型偏微分方程解的相关泛函。特别地,证明了实现$\\varepsilon$均方根误差的复杂度为$$O(\\varepsilon ^{-2}、\\124;\\!\\ log\\varepsilon ^ 3)$。
