# The Regulators of Beilinson and Borel

Share this page
*José I. Burgos Gil*

A co-publication of the AMS and Centre de Recherches Mathématiques

This book contains a complete proof of the fact that Borel's regulator map is
twice Beilinson's regulator map. The strategy of the proof follows the argument
sketched in Beilinson's original paper and relies on very similar descriptions
of the Chern-Weil morphisms and the van Est isomorphism.

The book has two different parts. The first one reviews the material from
algebraic topology and Lie group theory needed for the comparison theorem.
Topics such as simplicial objects, Hopf algebras, characteristic classes, the
Weil algebra, Bott's Periodicity theorem, Lie algebra cohomology, continuous
group cohomology and the van Est Theorem are discussed.

The second part contains the comparison theorem and the specific material
needed in its proof, such as explicit descriptions of the Chern-Weil morphism
and the van Est isomorphisms, a discussion about small cosimplicial algebras,
and a comparison of different definitions of Borel's regulator.

Titles in this series are co-published with the Centre de Recherches Mathématiques.

#### Readership

Graduate students and research mathematicians interested in number theory.

#### Reviews & Endorsements

Contains a lot of expository material, … The monograph is extremely valuable, not only in settling the question but in doing so in a readable way.
