This volume higlights progress in the theory regulators and secondary invariants, bringing together concepts, methods, results from analysis, differential geometry, algebraic geometry and number theory. A historical and mathematical overview of the theory of regulators is presented followed by articles written and refereed by experts in their respective fields.

This book is an outgrowth of the Workshop on "Regulators in Analysis, Geom- etry and Number Theory" held at the Edmund Landau Center for Research in Mathematical Analysis of The Hebrew University of Jerusalem in 1996. During the preparation and the holding of the workshop we were greatly helped by the director of the Landau Center: Lior Tsafriri during the time of the planning of the conference, and Hershel Farkas during the meeting itself. Organizing and running this workshop was a true pleasure, thanks to the expert technical help provided by the Landau Center in general, and by its...
