A note on rank 1 log extendable isocrystals on simply connected open varieties

Algebraic Geometry 2018-02-07 v2

Abstract

In 2010 de Jong proposed a pp-adic version of Gieseker's conjecture: if XX is a smooth, simply connected projective variety, then any isocrystal on XX is constant. This was proven by Esnault and Shiho under some additional assumptions. We show that the conjecture holds in the case of a non-proper variety with trivial tame fundamental group and for rank 1 log extendable isocrystals.
