晶体群与$\mathrm{III}_0$型的Calabi-Yau 3-折叠

Crystallographic Groups and Calabi-Yau 3-folds of Type $\mathrm{III}_0$

Christian Gleißner, Julia Kotonski

摘要:

本文给出了具有孤立奇点的三维阿贝尔簇的Gorenstein代数的精细分类,直到双全纯和同胚。这改进了Oguiso和Sakurai关于$\mathrm{III}_0$型的Calabi-Yau三重折叠的一个结果。我们的证明依赖于晶体群理论的方法应用到orbifold的基本群,这样的晶体。

英文摘要:

We provide a fine classification of Gorenstein quotients of three-dimensional abelian varieties with isolated singularities, up to biholomorphism and homeomorphism. This refines a result of Oguiso and Sakurai about fibred Calabi-Yau threefolds of type $\mathrm{III}_0$. Our proof relies on methods of crystallographic group theory applied to the orbifold fundamental groups of such quotients.
