Slope filtrations in families

Algebraic Geometry 2012-01-04 v3 Number Theory

Abstract

This paper concerns arithmetic families of φ\varphi-modules over reduced affinoid spaces. For such a family, we first prove that the slope polygons is lower semicontinuous around any rigid point. If the slope polygons are locally constant around a rigid point, we further prove that around this point, the family has a global slope filtration after base change to some extended Robba ring.
