Riassunto

This book contains four contributions in the field of dynamical systems. The topics treated are also related to topology, Hamiltonian systems and stochastics. All the authors give a careful readable presentation of recent research results, addressed to graduate students and researchers in these fields; the book is also suitable as a text for graduate level seminars in dynamical systems.
