摘要

设 $X$ 是在 ${{mathbb{C}}$ 上局部有限类型的连通方案,并设 $X^{textrm{an}$ 是其相关的解析空间。在本文中,我们定义了一个从 $X^{\textrm{an}$ 的拓扑基群到 $X$ 的近似基群的比较映射。

A Comparison Theorem For The Pro-étale Fundamental Group
Let $X$ be a connected scheme locally of finite type over ${\mathbb{C}}$, and let $X^{\textrm{an}}$ be its associated analytic space. In this paper, we define a comparison map from the topological fundamental group of $X^{\textrm{an}}$ to the pro-étale fundamental group of $X$.
