Ju-Yi Yen, Marc Yor - Local Times and Excursion Theory for Brownian Motion: A Tale of Wiener and Itô Measures
Published: 2013-10-16 | ISBN: 331901269X | PDF | 135 pages | 0.9 MB
This monograph discusses the existence and regularity properties of local times associated to a continuous semimartingale, as well as excursion theory for Brownian paths. Realizations of Brownian excursion processes may be translated in terms of the realizations of a Wiener process under certain conditions. With this aim in mind, the monograph presents applications to topics which are not usually treated with the same tools, e.g.: arc sine law, laws of functionals of Brownian motion, and the Feynman-Kac formula.
