用Tate normal form计算椭圆曲线的有理挠率

Computing the rational torsion of an elliptic curve using Tate normal form

I. García, M. A. Olalla Acosta, J. M. Tornero

摘要:

一个经典的结果(显然是由于泰特)是所有扭点为n阶($4 \leq n \leq 10$,或n = 12)的椭圆曲线都在一个单参数族中。然而,这个事实似乎从来没有被用于计算椭圆曲线的挠率。我们在这里提出了一个非常实际的算法,使用这样一个家庭的存在。

英文摘要:

It is a classical result (apparently due to Tate) that all elliptic curves with a torsion point of order n ($4 \leq n \leq 10$, or n = 12) lie in a one-parameter family. However, this fact does not appear to have been used ever for computing the torsion of an elliptic curve. We present here a extremely down-to-earth algorithm using the existence of such a family.
