在11处具有坏约化的三个Calabi-Yau三重的模块性

On the modularity of three Calabi-Yau threefolds with bad reduction at 11

Matthias Schuett

摘要:

我们研究了三个非刚性的Calabi-Yau三重的模性,这些三重在11处具有坏约化,它们是有理椭圆曲面的纤维积。为此,我们应用Serre的方法比较了具有不均匀迹的二维2-adic伽罗瓦表示。因此,我们将三重中的两重(或者更准确地说,它们的中间上同调群的二维部分)分别与权重为4、水平为22和55的新形式相关联。这使我们能够计算这些变种的zeta函数,直到坏素数的欧拉因子。

英文摘要:

We investigate the modularity of three non-rigid Calabi-Yau threefolds with bad reduction at 11 which arise as fibre products of rational elliptic surfaces. For this purpose, we apply a method by Serre to compare two-dimensional 2-adic Galois representations with uneven trace. Hereby, we associate two of the threefolds (or, more precisely, a two-dimensional piece of their middle cohomology group) to newforms of weight 4 and level 22 and 55, respectively. This enables us to compute the zeta-functions of these varieties up to the Euler factors of the bad primes.
