分数阶布朗运动的表示公式

Representation formulae for the fractional Brownian motion

Jean Picard

摘要:

我们讨论了分数布朗运动的一些经典表示之间的关系,作为一个随机积分相对于一个标准的布朗运动,或作为一个函数项级数与独立的高斯系数。介绍了研究所需的分数阶微积分的基本概念。作为应用,我们还证明了分式布朗运动的Cameron-Martin空间的一些性质,并将它的规律与它的某些变体的规律进行了比较。这里给出的几个结果并不是新的;我们的目的是对以前的一些文献提供一个统一的处理,并给出替代的证明和额外的结果;我们也试图尽可能独立。

英文摘要:

We discuss the relationships between some classical representations of the fractional Brownian motion, as a stochastic integral with respect to a standard Brownian motion, or as a series of functions with independent Gaussian coefficients. The basic notions of fractional calculus which are needed for the study are introduced. As an application, we also prove some properties of the Cameron-Martin space of the fractional Brownian motion, and compare its law with the law of some of its variants. Several of the results which are given here are not new; our aim is to provide a unified treatment of some previous literature, and to give alternative proofs and additional results; we also try to be as self-contained as possible.
