Equivariant Tamagawa Number Conjectures

(Un exposé de David Burns au séminaire de théorie des nombres de Chevaleret le 24 juin 2002)

Résumé :

 Over the last few years Flach and the author have together
formulated and studied a natural refinement of the seminal Tamagawa Number
Conjecture (as originally formulated by Bloch and Kato and then extended and
reworked by Fontaine and Perrin-Riou) in the context of motives with
(non-commutative) coefficients. We aim to describe the basic formalism of
this equivariant refinement, review some of the currently available evidence
(in particular, in the context of Tate motives) and briefly explain some
striking connections to certain other well known and more explicit
conjectures (for example, of Mazur-Tate, Bertolini-Darmon, Gross,
Gross-Tate, Rubin, Brumer, Coates-Sinnott, Chinburg..)
