Refined theorems of the Birch and Swinnerton-Dyer type

Ki-Seng Tan (1995)

Annales de l'institut Fourier

Similarity:

In this paper, we generalize the context of the Mazur-Tate conjecture and sharpen, in a certain way, the statement of the conjecture. Our main result will be to establish the truth of a part of these new sharpened conjectures, provided that one assume the truth of the classical Birch and Swinnerton-Dyer conjectures. This is particularly striking in the function field case, where these results can be viewed as being a refinement of the earlier work of Tate and Milne.

p -adic Abelian Stark conjectures at s = 1

David Solomon (2002)

Annales de l’institut Fourier

Similarity:

A p -adic version of Stark’s Conjecture at s = 1 is attributed to J.-P. Serre and stated (faultily) in Tate’s book on the Conjecture. Building instead on our previous paper (and work of Rubin) on the complex abelian case, we give a new approach to such a conjecture for real ray-class extensions of totally real number fields. We study the coherence of our p -adic conjecture and then formulate some integral refinements, both alone and in combination with its complex analogue. A ‘Weak Combined...

Some results and problems that arise in connection with the foundations of the theory of ruled and rational field extensions are discussed.
