Author Description

On June 7-9, 2004, a conference on Dynamical Systems and Diophantine Approximation was held at the Institut Henri Poincare. One of the aims of this conference was to give a survey of research tools at the interface between these two domains. The editors' goal was also to highlight methods and open questions. The proceedings the editors are presenting in this volume reflect the spirit of this conference. The reader will find surveys and articles on the convergence or divergence points between dynamical systems and Diophantine approximation. All the papers are accessible to a wide audience.
