Nontorsion Points of Low Height on Elliptic Curves over Quadratic Fields

Number Theory 2011-11-11 v1 Algebraic Geometry

Abstract

We give examples of points with particularly low height on elliptic curves over quadratic fields, recovered by a search over elliptic divisibility sequences. The smallest example identified satisfies dh(P)=0.0077127...: improving on the previous smallest for curves over quadratic fields of dh(P)=0.0194426... given by Everest and Ward; and comparable with some of the examples of smallest height on curves over Q tabulated by Elkies.
