摘要翻译:
我们证明了通过复数(抽象域)的自同构共轭可以改变C上局部对称簇的拓扑基本群。因此,我们得到了定义在数域上的一大类代数簇,其性质是数域在C中的不同嵌入给出了具有非同构基本群的复簇。

英文摘要:
We show that conjugation by an automorphism of the complex numbers (as an abstract field) may change the topological fundamental group of a locally symmetric variety over C. As a consequence, we obtain a large class of algebraic varieties defined over number fields with the property that different embeddings of the number field into C give complex varieties with nonisomorphic fundamental groups.
