The relative Hodge–Tate spectral sequence for rigid analytic spaces

Authored by

Abstract

We construct a relative Hodge–Tate spectral sequence for any smooth proper morphism of rigid analytic spaces over a perfectoid field extension of (Formula presented.). To this end, we generalise Scholze's strategy in the absolute case by using smoothoid adic spaces. As our main additional ingredient, we prove a perfectoid version of Grothendieck's “cohomology and base-change”. We also use this to prove local constancy of Hodge numbers in the rigid analytic setting, and deduce that the relative Hodge–Tate spectral sequence degenerates.
