PREFACE

These Conference Proceedings contain written versions of most of the contributions presented at the 5th International Conference on Differential Geometry and Its Applications, held in Opava (Czechoslovakia), August 24-28, 1992, in the site of the newly established Silesian University at Opava (founded 1990).

The Conference provided a setting for discussing recent developments in Differential Geometry (Section A) and Geometrical Methods in Physics (Section B). There were main lectures during the mornings and short talks on more specialized topics in the afternoons.

The members of the Organizing Committee were Jarolim Bures, Anton Dekret, Josef Janyska, Ivan Kolar, Oldrich Kowalski, Demeter Krupka (Chairman), Zbynek Nadenik, Jan Novotny, and Jiri Vanzura. The program organizers for the sections A and B were Oldrich Kowalski and Ivan Kolar.
