设K为数域。在本文中,我们感兴趣的问题是:是否存在一个仅依赖于K的常数Ck,使得对于定义在K上的任何半稳定椭圆曲线,当p是大于Ck的素数时,其p-扭点上的Galois表示是不可约的?如果答案是肯定的,我们怎么能得到这样的常量呢?我们证明了当K满足一定条件时,解是肯定的,并且我们显式地得到了Ck。此外,我们还证明了该条件在许多情况下都是可实现的。
Let K be a number field. In this paper, we are interested in the following problem: does there exist a constant cK, which depends only on K, such that for any semi-stable elliptic curve defined over K, the Galois representation in its p-torsion points is irreducible whenever p is a prime number greater than cK? In case the answer is positive, how can we get such a constant? We prove that if a certain condition is satisfied by K, the answer is positive and we obtain cK explicitly. Furthermore, we prove that this condition is realized in many situations.
