this volume gives an account of new and recent developments in the theory of random and, in particular, stochastic dynamical systems. its purpose is to document and, to some extent, summarise the current state of the field of random dynamical systems beyond the recent monograph, random dynamical systems by ludwig arnold. the book is intended for an audience of researchers and graduate students from stochastics as well as dynamics. it contains carefully refereed contributions from experts in the field, chosen such that a consistent picture can be given. recent results on stochastic bifurcation, hyperbolic systems, numerics and asymptotics, more general driving processes for stochastic differential equations, and stochastic analysis on infinite-dimensional manifolds are presented in a comprehensible manner. several new and exciting insights int o the unexpected variety of dynamical behaviours resulting from the influence of stochastic perturbations are conveyed to the reader.
