| Jun 8, 2020 at 11:29 | comment | added | user39380 | @YCor Yes, thanks for clarification! (Here is a related question on etale fundamental group mathoverflow.net/questions/223885/… where the answer is positive) | |
| Jun 8, 2020 at 11:10 | comment | added | YCor | As it may puzzle some readers: "topological fundamental group" should be understood as "fundamental group" in the sense of topology. It's used in complex geometry to distinguish with the étale fundamental group. It's unrelated to the topological fundamental group in any meaning where it refers to some topology on the fundamental group (which is relevant for spaces that are locally complicated such as Hawaiian earrings). | |
