3 PREFACE The 1980 conference on "Differential Geometric Methods in Mathematical Physics" at the Technical University of Clausthal, FRG, was part of the by now fairly long series of conferences on similar themes. Initiated by K. Bleuler in 1973 (Bonn) and continued in Bonn (1975, 1977), Aix-en-Provence (1974, 1979), Warsaw (1976), Clausthal (1978) and Salamanca (1979), these conferences have gathered a large number of prominent researchers in this special branch of mathematics/mathematical physics. No doubt, these conferences have become something of an institution. As a tribute to one of the initiators of this series of conferences, one session was dedicated to K. Bleuler on the occasion of his retirement. Additionally, the 1980 conference also pursued a more local, Clausthal tradition of summer schools and meetings on special problems in mathematical physics. The topics covered in this year's conference and in the attached workshop which are included in this volume could, roughly speaking, be described by the following keywords: symplectic category, differential operators on manifolds and vector bundles, mathematics of (non-abelian) gauge fields, geometric quantization and asymptotic expansions, all of which are, of course, central issues in the contemporary differential geometric-biased approach to a variety of mathematical questions in classical and quantum physics. Notable achievements were, more specifically, reports on the a s y m ~ t for o t spherical i c s functions, bifurcation theory, mathematical structure of gauge theories, spacetime geometry and representation theory. The editors rearet that due to a general editorial requirement of homogeneity in a lecture notes volume, which applies also for these proceedings, it was not possible to include contributions (invited talks as well as contributed papers) with a very strong bias towards physics or having definitely the form of a pure review paper or of a research announcement. In some other

4 IV cases manucripts were not received in time. Acknowledgments We wish to express our gratitude to the following persons and organizations for financial support and for other assistance rendering the publication of this proceedings volume possible: - Der NiedersKchische Minster fur Wissenschaft und Kunst, - Alexander von Humboldt-Stiftung, Bonn. We thank especially, for generous grants - The Office for Foreign Studies and Activities at the Techn.Univ. of Clausthal (Prof.Dr. H.Quade and Dr. R.Pestel) and - The Volkswagen Foundation. We also want to thank Springer Verlag, Heidelberg, for their kind assistance in matters of publication. Last but not least, we whish to thank Mrs. J. Gardiner, Institut fur Theoretische Physik der TU Clausthal, for an exellent and speedy complete preparation of this volume, as well as the other members of the institute whose help made the organization smooth and efficient.
