Stochastic Analysis and Related Topics Vi: Proceedings of the Sixth Oslo-Silivri Workshop Geilo 1996: 42 (Progress in Probability) - Softcover

This volume contains the contributions of the participants of the Sixth Oslo-Silivri Workshop on Stochastic Analysis, held in Geilo from July 29 to August 6, 1996. There are two main lectures · Stochastic Differential Equations with Memory, by S.E. A. Mohammed, · Backward SDE's and Viscosity Solutions of Second Order Semilinear PDE's, by E. Pardoux. The main lectures are presented at the beginning of the volume. There is also a review paper at the third place about the stochastic calculus of variations on Lie groups. The contributing papers vary from SPDEs to Non-Kolmogorov type probabilistic models. We would like to thank · VISTA, a research cooperation between Norwegian Academy of Sciences and Letters and Den Norske Stats Oljeselskap (Statoil), · CNRS, Centre National de la Recherche Scientifique, · The Department of Mathematics of the University of Oslo, · The Ecole Nationale Superieure des Telecommunications, for their financial support.

Stochastic analysis has proved to be one of the most widely applicable mathematical tools available to researchers in a variety of scientific and engineering disciplines. One of the most challenging subjects in relation to physics concerns an analysis of heat kernels on infinite dimensional manifolds. The simplest nontrivial case is that of the path and loop space on a Lie group. In this volume an up-to-date survey of this topic is given by L. Gross. Another concise but complete survey of the Hausdorff measure on Wiener space and its applications to Malliavin Calculus is given by D. Feyel. Other survey articles deal with a variety of rich topics: * short time asymptotics of diffusion processes with values in infinite dimensional manifolds * large deviations of diffusions with discontinuous drifts * stochastic integration with respect to the fractional Brownian motion (which is not a semimartingale) * Stokes' formula for the Brownian sheet * a new family of logarithmic Sobolev inequalities via the Girsanov Theorem The broad coverage of various subjects demonstrates the powerful stochastic techniques of prominent researchers. This volume is an outgrowth of the Seventh Silivri Workshop. It will serve as a good reference text for graduate students and those working in stochastic analysis, as well as mathematical economists treating modeling systems with long memory. Contributors: S.
