Series Preface
The Centre de recherches mathematiques (CRM) was created in 1968 bythe Universite de Montreal to promote research in the mathematical sciences. It is now a national institute that hosts several groups, holds specialtheme years, summer schools, workshops, and a postdoctoral program. Thefocus of its scientific activities ranges from pure to applied mathematics,and includes statistics, theoretical computer science, mathematical methods in biology and life sciences, and mathematical and theoretical physics.The CRM also promotes collaboration between mathematicians and industry. It is subsidized by the Natural Sciences and Engineering ResearchCouncil of Canada, the Fonds FCAR of the Province of Quebec, the Canadian Institute for Advanced Research and has private endowments. Currentactivities, fellowships, and annual reports can be found on the CRM webpage at http://www .CRM.UMontreal.CAl.The CRM Series in Mathematical Physics includes monographs, lecturenotes, and proceedings based on research pursued and events held at theCentre de recherches mathematiques.

Preface
Solitons were discovered by John Scott Russel in 1834 and have interestedscientists and mathematicians ever since. They have been the subject of alarge body of research in a wide variety of fields of physics and mathematics,not to mention engineering and other branches of science such as biology.The workshop, "Solitons: Properties, Dynamics, Interactions, Applica
tions" was held at Queen's University, Kingston, Canada over the periodJuly 20-26, 1997. It was conceived as an interdisciplinary meeting whereintop researchers from several of these fields could meet, interact, and exchange ideas across traditional boundaries of research. During the workshop, research was presented on mathematical and numerical aspects of solitons, as well as on applications of solitons to nuclear and particle physics,cosmology, condensed matter physics, and to the recent developments instring theory.This volume consists of written versions of all talks presented at theworkshop. It is our hope that people with an interest in solitons in virtuallyany field of research will find the range of topics discussed both interestingand inspiring.
