Séminaire de probabilités XLI

Stochastic processes are as usual the main subject of the S?minaire, with contributions on Brownian motion (fractional or other), L?vy processes, martingales and probabilistic finance. Other probabilistic themes are also present: large random matrices, statistical mechanics. The contributions in this volume provide a sampling of recent results on these topics. All contributions with the exception of two are written in English language.
