Abstract

We develop a full 6-functor formalism for pp-torsion \'etale sheaves in rigid-analytic geometry. More concretely, we use the recently developed condensed mathematics by Clausen--Scholze to associate to every small v-stack (e.g. rigid-analytic variety) XX with pseudouniformizer π\pi an \infty-category Da(OX+/π)\mathcal D^a_\square(\mathcal O^+_X/\pi) of "derived quasicoherent complete topological OX+/π\mathcal O^+_X/\pi-modules" on XX. We then construct the six functors \otimes, Hom\underline{Hom}, ff^*, ff_*, f!f_! and f!f^! in this setting and show that they satisfy all the expected compatibilities, similar to the \ell-adic case. By introducing φ\varphi-module structures and proving a version of the pp-torsion Riemann-Hilbert correspondence we relate OX+/π\mathcal O^+_X/\pi-sheaves to Fp\mathbb F_p-sheaves. As a special case of this formalism we prove Poincar\'e duality for Fp\mathbb F_p-cohomology on rigid-analytic varieties. In the process of constructing Da(OX+/π)\mathcal D^a_\square(\mathcal O^+_X/\pi) we also develop a general descent formalism for condensed modules over condensed rings.
