Abstract
Up to now the Beilinson conjectures gave the values of the leading term of the L-function of an arithmetic variety only up to some non-zero rational number. Bloch & Kato have removed this ambiguity by defining Tamagawa numbers for motives, and Fontaine & Perrin-Rion extended this work to a series of conjectures about mixed motives. Whereas in the Bloch-Kato conjecture there is still some K-theory, this no longer occurs in the work of Fontaine & Perrin-Riou, except possibly in the ultimate definition of a mixed motive. This remains a serious problem.KeywordsAbelian VarietySmooth Projective VarietyMotivic PairMotivic CategoryFinite PlaceThese keywords were added by machine and not by the authors.
