This e-book is an outgrowth of the Workshop on "Regulators in research, Geom etry and quantity idea" held on the Edmund Landau middle for study in Mathematical research of The Hebrew college of Jerusalem in 1996. through the coaching and the maintaining of the workshop we have been enormously helped through the director of the Landau middle: Lior Tsafriri throughout the time of the making plans of the convention, and Hershel Farkas through the assembly itself. Organizing and working this workshop was once a real excitement, due to the professional technical support supplied through the Landau middle commonly, and through its secretary Simcha Kojman specifically. we wish to specific our hearty because of them all. besides the fact that, the articles assembled within the current quantity don't symbolize the lawsuits of this workshop; neither might all individuals to the e-book make it to the assembly, nor do the contributions herein unavoidably mirror talks given in Jerusalem. within the advent, we define our view of the idea to which this quantity intends to give a contribution. The the most important target of the current quantity is to compile options, tools, and effects from research, differential in addition to algebraic geometry, and quantity concept with a purpose to paintings in the direction of a deeper and extra accomplished knowing of regulators and secondary invariants. Our thank you visit the entire members of the workshop and authors of this quantity. may perhaps the readers of this publication get pleasure from and cash in on the mix of mathematical rules right here documented.
