二次域上椭圆曲线的低高无挠点

Nontorsion Points of Low Height on Elliptic Curves over Quadratic Fields

Graeme Taylor

摘要:

我们给出的例子,特别是低高度的椭圆曲线上的二次域,恢复通过搜索椭圆整除序列。识别的最小示例满足dh(P)=0.0077127.:改进了dh(P)=0.0194426的二次域上曲线的先前最小值. Everest和Ward给出的;并且与Elkies列出的关于Q的曲线上最小高度的一些示例相当。

英文摘要:

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.
