Prologue.- Gravity and Cosmology - Classical and Quantum Aspects.- Quantum Mechanics in Between - Decoherence and Determinism.- Decoherence in Mesoscopic Systems.- Entropy, Chaos and Complexity.

The contributions to this volume are based on selected lectures from the first international workshop on decoherence, information, complexity and entropy (DICE). The aim of this volume is to reflect the growing importance ot common concepts behind seemingly different fields such as quantum mechanics, general relativity and statistical physics in a form accessible to nonspecialist researchers. Many presentations include original results which are published here for the first time.
