Cristallinity of rigid flat connections revisited

Algebraic Geometry 2023-11-23 v2 Number Theory

Abstract

We generalise a theorem on the existence of Frobenius isocrystal and Fontaine-Laffaille module structures on rigid flat connections to the non-proper setting. The proof is based on a new strategy of a point-set topological flavour, which allows us to produce a purely pp-adic statement and thereby to avoid the classical Simpson correspondence.
