粗糙抛物型方程的数值格式

Numerical Schemes for Rough Parabolic Equations

Aurélien Deya

摘要:

本文研究了一类(0,1)上受非线性粗糙信号扰动的抛物型方程的数值逼近格式。它是文[8,7]的继续,其中建立了解的存在性和唯一性。该方法结合了粗糙路径方法与离散随机偏微分方程的标准考虑。结果适用于几何2-粗糙路径,它涵盖了Hurst指数H \textgreater{} 1/3的多维分数布朗运动的情况。

英文摘要:

This paper is devoted to the study of numerical approximation schemes for a class of parabolic equations on (0, 1) perturbed by a non-linear rough signal. It is the continuation of [8, 7], where the existence and uniqueness of a solution has been established. The approach combines rough paths methods with standard considerations on discretizing stochastic PDEs. The results apply to a geometric 2-rough path, which covers the case of the multidimensional fractional Brownian motion with Hurst index H \textgreater{} 1/3.
