算术环上阿贝尔簇中的光滑超曲面

Smooth hypersurfaces in abelian varieties over arithmetic rings

Ariyan Javanpeykar, Siddharth Mathur

摘要:

设$A$是特征为零的$\mathbb{Z}$ -正则生成整环$R$上的一个至少四维的阿贝尔格式,$L$是$A$上的一个样本线丛.证明了在$A$中表示$L$的光滑超曲面$D$的集合是有限的,并证明了这种超曲面的模栈只有1000个$R$ -点.我们通过使用水平结构来实现这一点,插值有限的结果之间的模量堆叠和堆叠的正则极化品种。

英文摘要:

Let $A$ be an abelian scheme of dimension at least four over a $\mathbb{Z}$-finitely generated integral domain $R$ of characteristic zero, and let $L$ be an ample line bundle on $A$. We prove that the set of smooth hypersurfaces $D$ in $A$ representing $L$ is finite by showing that the moduli stack of such hypersurfaces has only finitely many $R$-points. We accomplish this by using level structures to interpolate finiteness results between this moduli stack and the stack of canonically polarized varieties.
