摘要

利用超越方法确定了极化阿别列格式的模堆的Artin-Mazur 同伦型，并推导了这些模堆的基本群的一些算术性质。最后，从一个可变同伦的角度分析了代数曲线模堆与主极化阿贝尔格式之间的Torelli态射。

Étale homotopy types of moduli stacks of polarised abelian schemes

We determine the Artin–Mazur étale homotopy types of moduli stacks of polarised abelian schemes using transcendental methods and derive some arithmetic properties of the étale fundamental groups of these moduli stacks. Finally we analyse the Torelli morphism between the moduli stacks of algebraic curves and principally polarised abelian schemes from an étale homotopy point of view.
