Congruences between Heegner points and quadratic twists of elliptic curves
arXiv:1606.03172
Abstract
We establish a congruence formula between -adic logarithms of Heegner points for two elliptic curves with the same mod Galois representation. As a first application, we use the congruence formula when to explicitly construct many quadratic twists of analytic rank zero (resp. one) for a wide class of elliptic curves . We show that the number of twists of up to twisting discriminant of analytic rank zero (resp. one) is , improving the current best general bound towards Goldfeld's conjecture due to Ono--Skinner (resp. Perelli--Pomykala). We also prove the 2-part of the Birch and Swinnerton-Dyer conjecture for many rank zero and rank one twists of , which was only recently established for specific CM elliptic curves .
