Chung's law for integrated brownian motion
WebJul 4, 2013 · We study some limit theorems for the normalized law of integrated Brownian motion perturbed by several examples of functionals: the first passage time, the nth passage time, the last passage time up to a finite horizon and the supremum. We show that the penalization principle holds in all these cases and give descriptions of the … WebMay 3, 2024 · In the present work the results of K. L.

Introduction Let (U;V) be the 2-dimensional process of integrated Brownian motion (IBM) andBrownian motion (BM), where Urepresents IBM and V represents BM. This process is often called the Kolmogorov difiusion since its study was apparently initiated by [7]. It is well-known (and easily verifled by computing expectations and covariances of …
