椭圆曲线上的有理点

Rational points on elliptic curves

Graham Everest, Jonathan Reynolds, Shaun Stevens

摘要:

本文研究了Weierstrass型椭圆曲线上有理点的结构。设x(P)=A_P/B_P^2表示有理点P的$x$ -坐标,则我们考虑B_P何时可以是素幂.利用Faltings定理,我们证明了对于一个大于1的固定幂,只有100个有理点.在下降通过一个issues是可能的,我们表明,没有限制的权力,只有100多个有理点,这些点是有界的数量在一个明确的方式,他们是有效的可计算的。

英文摘要:

We consider the structure of rational points on elliptic curves in Weierstrass form. Let x(P)=A_P/B_P^2 denote the $x$-coordinate of the rational point P then we consider when B_P can be a prime power. Using Faltings' Theorem we show that for a fixed power greater than 1, there are only finitely many rational points. Where descent via an isogeny is possible we show, with no restrictions on the power, that there are only finitely many rational points, these points are bounded in number in an explicit fashion, and that they are effectively computable.
