Abstract

Using the decomposition of Jacobians with group action, we prove the non-existence of some Shimura subvarieties in the moduli space of ppav \(A_{g}\) arising from families of dihedral and quaternionic covers of the complex projective line \({{\mathbb {P}}}^1\).

的雅可比矩阵和Shimura子变种的分解 \(A_g\)

利用具有群作用的雅可比矩阵的分解，证明了复射影线\({{\mathbb {P}}}^1\)的二面体覆盖族和四元数覆盖族在ppav \(A_{g}\)的模空间中不存在Shimura子簇。
