Preface

Quantum mechanics is a theory of a rich structure whose potential is far from exhausted. During its first decades the main areas of applications were in atomic and nuclear physics and through quantum field theory, also in the physics of el-ementary particles. More recently there is an emphasis in macroscopic quantum effects, condensed matter physics, and generally in areas of applied physics. The necessity of treating quantum systems from the first principles is not only a mathe-matician's desire for an "Ordnung", but it is increasingly important as the methods of studying quantum systems become more numerous and more complex.

The present volume collects some of the contributions presented at the confer-ence "QMath-8. Mathematical Results in Quantum Mechanics", held on December 10 - 14, 2001, at the facilities of Universidad Nacional Autonoma de Mexico, in Taxco, a fascinating colonial city of Mexico. There is also a paper by J. Bourgain, who was unable to attend, but submitted a manuscript.

Since the conference is the last one of a long series, it might be useful to recall briefly its history. It began in 1987 at the Laboratory of Theoretical Physics of the Joint Institute of Nuclear Research, in Dubna. The first meeting was small and topical, being devoted to applications of self-adjoint extensions in quantum physics. There was, at the time, the additional goal of finding new ways in which scientists from different parts of the world could collaborate. In the spring of 1990, the fourth conference met at the Liblice Castle near Prague. Under the new circumstances, it was decided to make the subject wider and to address all problems in quantum mechanics which can be studied by rigorous methods. Such a subject choice resonated within the community and the QMath series found a stable audience as the following meetings (Blossin 93, Ascona 96, and Prague 98) witnessed. With its eighth meeting, the series left Europe for the first time. Enough time has passed to look at the QMath series with some perspective. We believe that it plays a considerable role in the development of contemporary research in the mathematical physics of quantum mechanics, and we think that it can be already considered as a classical series of conferences.

The Taxco meeting was organized with the support of: Centro de Enseiianza para Extranjeros, Coordinacion de la Investigacion Cientifica, Direccion and Depar-tamento de Metodos Matematicos y Numericos of the Instituto de Investigaciones en Matematicas Aplicadas y en Sistemas, Direccion General de Asuntos del Per-sonal Academico (project, Ecuaciones Diferenciales y Fisica Matematica, PAPIIT IN 105799), Direccion General de Servicios de Computo Academico, and Secretaria Administrativa; all of them from Universidad Nacional Autonoma de Mexico. We also had the support of Consejo Nacional de Ciencia y Tecnologia (project, In-vestigacion en Matematicas Aplicadas y su Enseiianza) and Sociedad Matematica

X PREFACE

Mexicana. Several national science funds provided support for participants, in par-ticular the Czech and French ones. Last but not least, there was the hard work of the conference's secretary, Ana Mar!a Garda Ramirez, and the technical staff, Enrique Felipe Perez Garcia, Ricardo Federico Villarreal Martinez and Rodrigo Ca-margo Frias. We deeply thank them all for their support that made the success of QMath-8 possible.

At the same time, no conference can be successful without attentive participants who come with interesting talks and show activity in discussions. This was the case in Taxco, where we had a considerable number of young scientists, and we wish to thank all those who came, often a long way, and created an inspiring atmosphere. We are particularly grateful to the colleagues who have contributed to this volume and to the referees who reviewed the contributions rapidly but attentively.

This book contains contributions presented at the conference, "QMath-8: Mathematical Results in Quantum Mechanics", held at Universidap Nacional Aut6noma de Mexico in December 2001.

The articles cover a wide range of mathematical problems and focus on various aspects of quantum mechanics, quantum field theory, and nuclear physics. Topics vary from spectral properties of the SchrOdinger equation of various quantum systems to the analysis of quantum computation algorithms.

The book is suitable for graduate students and research mathematicians interested in the mathematical aspects of quantum mechanics.
