关于椭圆曲线挠率的概率局部-整体原理

On a probabilistic local-global principle for torsion on elliptic curves

John Cullinan, Meagan Kenney, John Voight

摘要:

设$m$是正整数,$E$是$\mathbb{Q}$上的椭圆曲线,且对素数$p$的密度集$1$,满足$m\mid#E(\mathbb{F}_p)$.在Katz和Harron-Snowden工作的基础上,我们研究了$m$整除$E(\mathbb{Q})$的挠子群阶的概率:我们发现对于所有$m \in \{ 1, 2, \dots, 10, 12, 16\}$它都是非零的,并且当$m \in \{ 1,2,3,4,5,7 \}$ .作为补充,我们给出了当参数化模曲线由亏格为零的无挠群的商产生时,具有额外层结构的椭圆曲线的渐近计数。

英文摘要:

Let $m$ be a positive integer and let $E$ be an elliptic curve over $\mathbb{Q}$ with the property that $m\mid#E(\mathbb{F}_p)$ for a density $1$ set of primes $p$. Building upon work of Katz and Harron-Snowden, we study the probability that $m$ divides the the order of the torsion subgroup of $E(\mathbb{Q})$: we find it is nonzero for all $m \in \{ 1, 2, \dots, 10, 12, 16\}$ and we compute it exactly when $m \in \{ 1,2,3,4,5,7 \}$. As a supplement, we give an asymptotic count of elliptic curves with extra level structure when the parametrizing modular curve arises from the quotient by a torsion-free group of genus zero.
