Commentaires: unesp2002 Workshop on Integrable Theories, Solitons and Duality 1-6 July 2002, São Paulo, Brazil The workshop is devoted to the research work being developed in some areas of Physics and Mathematics relevant for the understanding of non-perturbative aspects of Physical Theories. Special attention is given to the role of solitons, infinite symmetries, integrability structures and the construction of exact methods. Among the topics covered are: Two dimensional integrable models, Skyrmions, Monopoles, higher dimensional integrable theories, Lattice models, Form factors, Bethe ansatz, Duality, Strings and solitons, Models with boundaries, and integrable models with non-commutative geometries.
