Besides a series of six articles on Lévy processes, Volume 38 of the
Séminaire de Probabilités contains contributions whose topics range
from analysis of semi-groups to free probability, via martingale
theory, Wiener space and Brownian motion, Gaussian processes and
matrices, diffusions and their applications to PDEs. As do all
previous volumes of this series, it provides an overview on the
current state of the art in the research on stochastic processes.
