# Bäcklund and Darboux Transformations. The Geometry of Solitons

A co-publication of the AMS and Centre de Recherches Mathématiques

This book is devoted to a classical topic that has undergone rapid and fruitful
development over the past 25 years, namely Bäcklund and Darboux
transformations and their applications in the theory of integrable systems,
also known as soliton theory.

The book consists of two parts. The first is a series of introductory
pedagogical lectures presented by leading experts in the field. They are
devoted respectively to Bäcklund transformations of Painlevé
equations, to the dressing method and Bäcklund and Darboux
transformations, and to the classical geometry of Bäcklund transformations
and their applications to soliton theory. The second part contains original
contributions that represent new developments in the theory and applications of
these transformations.

Both the introductory lectures and the original talks were presented at an
International Workshop that took place in Halifax, Nova Scotia (Canada). This
volume covers virtually all recent developments in the theory and applications
of Bäcklund and Darboux transformations.

Titles in this series are co-published with the Centre de Recherches Mathématiques.

#### Readership

Graduate students and research mathematicians interested in dynamical systems, ergodic theory, and partial differential equations.
