We give a 3-descent procedure to bound and, in some cases, compute the 3-part of the Selmer and Tate-Shafarevich group of the curves y^2=x^3+a, a a nonzero integer. This enables us to verify the whole Birch and Swinnerton-Dyer conjecture for some of such curves.

Abstract
We give a 3-descent procedure to bound and, in some cases, compute the 3-part of the Selmer and Tate-Shafarevich group of the curves y^2=x^3+a, a a nonzero integer. This enables us to verify the whole Birch and Swinnerton-Dyer conjecture for some of such curves.File in questo prodotto:
