Esnault has some nice papers discussing the relationship between the stratified and etale fundamental group; Deligne's P^1\{0,1,\infty} paper discusses the relationship between various pro-unipotent incarnations of these groups. If you have a more specific question in mind, I can try to say a bit more. | |

| Sep 24, 2018 at 7:29 | comment | added | Niels | "fundamental group" is a bit vague IMHO : are you interested in étale fundamental groups, in fundamental group schemes, in motivic fundamental groups, or in whatever ? | |
