On the effective version of Serre's open image theorem

Jacob Mayle, Tian Wang

AI总结:

本文在广义黎曼假设下,给出了Serre开像定理中使无复乘椭圆曲线的模$\ell$伽罗瓦表示不满射的最大素数$\ell$的显式上界,该上界与导子对数呈线性关系。

摘要:

设$E/\mathbb{Q}$为无复乘的椭圆曲线。根据Serre开像定理,对于每个足够大的素数$\ell$,$E$的模$\ell$伽罗瓦表示$\overlineρ_{E, \ell}$是满射的。在广义黎曼假设下,我们给出了使$\overlineρ_{E, \ell}$不满射的最大素数$\ell$的显式上界,该上界与$E$的导子的对数呈线性关系。

英文摘要:

Let $E/\mathbb{Q}$ be an elliptic curve without complex multiplication. By Serre's open image theorem, the mod $\ell$ Galois representation $\overlineρ_{E, \ell}$ of $E$ is surjective for each prime number $\ell$ that is sufficiently large. Under the generalized Riemann hypothesis, we give an explicit upper bound on the largest prime $\ell$, linear in the logarithm of the conductor of $E$, such that $\overlineρ_{E, \ell}$ is nonsurjective.
