Discrete Integrable Systems This volume consists of a set of ten lectures conceived as both introduction and up to date survey on discrete integrable systems. It constitutes a companion book to Integrability of Nonlinear Systems (Springer Verlag 2004 LNP 638 ISBN 3 540 20630 2). Both volumes address primarily graduate students and nonspecialist researchers but will also benefit lecturers looking for suitable material for advanced courses and researchers interested in specific topics
