Tame fundamental groups of pure pairs and Abhyankar’s lemma
Let (R, m, k) be a strictly local normal k-domain of positive characteristic and P be a prime divisor on X = Spec R. We study the Galois category of finite covers over X that are at worst tamely ramified over P in the sense of Grothendieck-Murre.Assuming that (X, P …
