布朗运动积分的游程

Excursions of the integral of the Brownian motion

Emmanuel Jacob

摘要:

积分的布朗运动有时被称为朗之万过程。拉哈尔研究了几个漂移法律引起的后者。在这里,我们遵循皮特曼为一般平稳过程提出的一个不同的观点。我们首先构造了一个平稳Langevin过程,然后明确地确定了它的平稳漂移测度。然后,这是用来提供新的描述伊藤的行程措施的朗之万过程中反映在一个完全非弹性的边界,这是最近推出的Bertoin。

英文摘要:

The integrated Brownian motion is sometimes known as the Langevin process. Lachal studied several excursion laws induced by the latter. Here we follow a different point of view developed by Pitman for general stationary processes. We first construct a stationary Langevin process and then determine explicitly its stationary excursion measure. This is then used to provide new descriptions of Ito's excursion measure of the Langevin process reflected at a completely inelastic boundary, which has been introduced recently by Bertoin.
