Abstract
AbstractIn this article we prove exactness of the homotopy sequence of overconvergent fundamental groups for a smooth and projective morphism in characteristicp. We do so by first proving a corresponding result for rigid analytic varieties in characteristic$0$, following dos Santos [dS15] in the algebraic case. In characteristicp, we then proceed by a series of reductions to the case of a liftable family of curves, where we can apply the rigid analytic result. We then use this to deduce a Lefschetz hyperplane theorem for convergent fundamental groups, as well as a comparison theorem with the étale fundamental group.
