Etale fundamental groups of affinoid $p$-adic curves

Algebraic Geometry 2017-08-29 v5 Number Theory

Abstract

We prove that the geometric etale fundamental group of a (geometrically connected) rigid smooth pp-adic affinoid curve is a semi-direct factor of a certain profinite free group. We also prove that the maximal pro-pp (resp. maximal prime-to-pp) quotient of this geometric \'etale fundamental group is pro-pp free of infinite rank (resp. (pro-)prime-to-pp free of finite computable rank).
