分数阶时滞方程的Malliavin演算

Malliavin calculus for fractional delay equations

Jorge A. Leon, Samy Tindel

摘要:

本文研究了一类由参数大于1/2的Hölder连续函数驱动的Young时滞微分方程在Young积分下唯一解的存在性.然后得到了解的一些估计,从而证明了Hurst参数H>1/2的分数阶布朗运动(fBm)驱动的时滞微分方程的解具有光滑密度.为此,我们使用Malliavin演算的基础上的Frechet可微性的方向上的再生核希尔伯特空间与fBM。

英文摘要:

In this paper we study the existence of a unique solution to a general class of Young delay differential equations driven by a Hölder continuous function with parameter greater that 1/2 via the Young integration setting. Then some estimates of the solution are obtained, which allow to show that the solution of a delay differential equation driven by a fractional Brownian motion (fBm) with Hurst parameter H>1/2 has a smooth density. To this purpose, we use Malliavin calculus based on the Frechet differentiability in the directions of the reproducing kernel Hilbert space associated with fBm.
