数域上椭圆曲线模p伽罗瓦表示的乘性约化不可约性

Irreducibility of mod p Galois representations of elliptic curves with multiplicative reduction over number fields

Filip Najman, George C. Turcas

摘要:

本文证明了对于每一个整数$d \geq 1$,存在一个显式常数$B_d$,使得下列成立.令$K$是次数为$d$的数域,令$q > \max\{d-1,5\}$是在$K$中完全惰性的任意有理素数,而$E$是定义在$K$上的任意椭圆曲线,使得$E$在$q$之上的素数$\mathfrak q$处具有潜在的乘性约化。则对每一个有理素数$p> B_d$,$E$都有一个不可约模$p$伽罗瓦表示。这个结果在“模块化方法”中有丢番图应用。我们提出了一个这样的应用程序的形式的渐近版本的费马最后定理,还没有被覆盖在现有的文献。

英文摘要:

In this note we prove that for every integer $d \geq 1$, there exists an explicit constant $B_d$ such that the following holds. Let $K$ be a number field of degree $d$, let $q > \max\{d-1,5\}$ be any rational prime that is totally inert in $K$ and $E$ any elliptic curve defined over $K$ such that $E$ has potentially multiplicative reduction at the prime $\mathfrak q$ above $q$. Then for every rational prime $p> B_d$, $E$ has an irreducible mod $p$ Galois representation. This result has Diophantine applications within the "modular method". We present one such application in the form of an Asymptotic version of Fermat's Last Theorem that has not been covered in the existing literature.
