# Differential Geometry and Integrable Systems

Ideas and techniques from the theory of integrable systems are playing an
increasingly important role in geometry. Thanks to the development of tools
from Lie theory, algebraic geometry, symplectic geometry, and topology,
classical problems are investigated more systematically. New problems are also
arising in mathematical physics. A major international conference was held at
the University of Tokyo in July 2000. It brought together scientists in all of
the areas influenced by integrable systems. This book is the first of three
collections of expository and research articles.

This volume focuses on differential geometry. It is remarkable that many
classical objects in surface theory and submanifold theory are described as
integrable systems. Having such a description generally reveals previously
unnoticed symmetries and can lead to surprisingly explicit solutions. Surfaces
of constant curvature in Euclidean space, harmonic maps from surfaces to
symmetric spaces, and analogous structures on higher-dimensional manifolds are
some of the examples that have broadened the horizons of differential geometry,
bringing a rich supply of concrete examples into the theory of integrable
systems.

Many of the articles in this volume are written by prominent researchers and
will serve as introductions to the topics. It is intended for graduate students
and researchers interested in integrable systems and their relations to
differential geometry, topology, algebraic geometry, and physics.

The second volume from this conference, also available from the AMS, is
