Erman Isik, Yasemin Kara, Ekin Ozman

摘要:

本文利用模方法证明了丢番图方程$x^p+y^p=z^3$在各种数域上的解的结果。首先,通过假设一些标准的模猜想,证明了满足一定技术条件的窄类数的一般数域的一个渐近结果。其次,我们证明了存在一个显式的界,使得方程$x^p+y^p=z^3$在$K=\Q(\sqrt{-d})$上没有特定类型的解,其中$d=1,7,19,43,67$,只要$p$大于这个界。在证明过程中,我们证明了关于伽罗瓦表示的不可约性、惯性群的象和Bianchi新形的各种结果。

英文摘要:

In this paper, we prove results about solutions of the Diophantine equation $x^p+y^p=z^3$ over various number fields using the modular method. Firstly, by assuming some standard modularity conjecture we prove an asymptotic result for general number fields of narrow class number one satisfying some technical conditions. Secondly, we show that there is an explicit bound such that the equation $x^p+y^p=z^3$ does not have a particular type of solution over $K=\Q(\sqrt{-d})$ where $d=1,7,19,43,67$ whenever $p$ is bigger than this bound. During the course of the proof we prove various results about the irreducibility of Galois representations, image of inertia groups and Bianchi newforms.
