用Volterra表示构造分数布朗运动上的粗糙路

A construction of the rough path above fractional Brownian motion using Volterra's representation

David Nualart, Samy Tindel

摘要:

本文利用分数布朗运动$B$的Volterra-Gaussian过程表示,构造了具有任意Hurst参数$H\in(0,1)$的多维分数布朗运动$B$上的粗路.这种方法对[随机过程]产生了一些代数和计算上的简化。120(2010)1444- 1472],其中首次引入了在$B$上的粗糙路径的构造。

英文摘要:

This note is devoted to construct a rough path above a multidimensional fractional Brownian motion $B$ with any Hurst parameter $H\in(0,1)$, by means of its representation as a Volterra Gaussian process. This approach yields some algebraic and computational simplifications with respect to [Stochastic Process. Appl. 120 (2010) 1444--1472], where the construction of a rough path over $B$ was first introduced.
