椭圆曲线上点的$ϕ_{n}$和$ψ_{n}^{2}$的最大公共赋值

The greatest common valuation of $ϕ_{n}$ and $ψ_{n}^{2}$ at points on elliptic curves

Paul Voutier, Minoru Yabuta

摘要:

给定椭圆曲线的极小模型$E/K$,在${\mathbb Q}_{p}$的有限扩张$K$上,对于任意有理素数$p$和任意无限阶点$P \in E(K)$,我们精确地确定了$\min \left( v \left( ϕ_{n}(P) \right), v \left( ψ_{n}^{2}(P) \right) \right)$,其中$v$是$K$上的归一化赋值,而$ϕ_{n}(P)$和$ψ_{n}(P)$是该曲线模型乘以$n$所产生的多项式。

英文摘要:

Given a minimal model of an elliptic curve, $E/K$, over a finite extension, $K$, of ${\mathbb Q}_{p}$ for any rational prime, $p$, and any point $P \in E(K)$ of infinite order, we determine precisely $\min \left( v \left( ϕ_{n}(P) \right), v \left( ψ_{n}^{2}(P) \right) \right)$, where $v$ is a normalised valuation on $K$ and $ϕ_{n}(P)$ and $ψ_{n}(P)$ are polynomials arising from multiplication by $n$ for this model of the curve.
