摘要

摘要研究了形式为$$(\mathbb {P}^3,\Delta )$$ (p3， Δ)的对数Calabi-Yau对，其中$$\Delta $$ Δ是一个四次曲面，并对所有小于或等于1的对数Calabi-Yau对进行了分类，直到保持体积等价。特别地，如果$$(\mathbb {P}^3,\Delta )$$ (p3， Δ)是一个极大对数Calabi-Yau对，那么我们证明它具有一个环面模型。

Quartic surfaces up to volume preserving equivalence

Abstract We study log Calabi–Yau pairs of the form $$(\mathbb {P}^3,\Delta )$$ ( P 3 , Δ ) , where $$\Delta $$ Δ is a quartic surface, and classify all such pairs of coregularity less than or equal to one, up to volume preserving equivalence. In particular, if $$(\mathbb {P}^3,\Delta )$$ ( P 3 , Δ ) is a maximal log Calabi–Yau pair then we show that it has a toric model.
