椭圆曲线上整点的重数

Multiples of integral points on elliptic curves

Patrick Ingram

摘要:

如果$E$是定义在$\ZZ$上的极小椭圆曲线,则我们得到一个仅依赖于$E$的全局Tamagawa数的约束$C$,使得对于任何点$P\in E(\QQ)$,$nP$对于至多一个$n>C$值是整数。作为推论,我们证明了,如果$E/\QQ$是一个固定的椭圆曲线,那么对于所有扭转$E'$的$E$的足够的高度,和所有扭转免费,秩一子群$Γ\subseteq E'(\QQ)$,$Γ$包含最多6个整点。包括全等数曲线的显式计算。

英文摘要:

If $E$ is a minimal elliptic curve defined over $\ZZ$, we obtain a bound $C$, depending only on the global Tamagawa number of $E$, such that for any point $P\in E(\QQ)$, $nP$ is integral for at most one value of $n>C$. As a corollary, we show that if $E/\QQ$ is a fixed elliptic curve, then for all twists $E'$ of $E$ of sufficient height, and all torsion-free, rank-one subgroups $Γ\subseteq E'(\QQ)$, $Γ$ contains at most 6 integral points. Explicit computations for congruent number curves are included.
