关于Enriques曲面的Shafarevich猜想

On the Shafarevich conjecture for Enriques surfaces

Teppei Takamatsu

摘要:

Enriques曲面是Kodaira维数$0$与$b_{2}=10$的极小曲面。如果我们在远离$2$的特征域上工作,Enriques曲面允许双重覆盖,这是K3曲面。本文通过将Shafarevich猜想转化为K3曲面的情形,证明了关于Enriques曲面的Shafarevich猜想.在我们的Shafarevich猜想的公式中,我们使用了“允许上同调好K3覆盖”的概念,它不仅包括好约化,而且包括花盆约化。

英文摘要:

Enriques surfaces are minimal surfaces of Kodaira dimension $0$ with $b_{2}=10$. If we work with a field of characteristic away from $2$, Enriques surfaces admit double covers which are K3 surfaces. In this paper, we prove the Shafarevich conjecture for Enriques surfaces by reducing the problem to the case of K3 surfaces. In our formulation of the Shafarevich conjecture, we use the notion "admitting a cohomological good K3 cover", which includes not only good reduction but also flower pot reduction.
