Visualizing elements of order
$7$ in the Tate–Shafarevich group of an elliptic curve
Published online by Cambridge University Press: 26 August 2016
Abstract
We study the elliptic curves in Cremona’s tables that are predicted by the Birch–Swinnerton-Dyer conjecture to have elements of order $7$ in their Tate–Shafarevich group. We show that in many cases these elements are visible in an abelian surface or abelian 3-fold.
