摘要:In this talk I will present the theory of the pro-étale fundamental group constructed by Bhatt and Scholze which is aimed to classify infinite étale covers. Then I will give a description of this fundamental group for schemes whose singular locus is 0-dimensional. I will also introduce a specialization theorem for the pro-étale fundamental group whose parallel in the case of Grothendieck's étale fundamental group played a very important role in arithmetic algebraic geometry.
