Derived $\mathcal{O}_k$-adic geometry and derived Raynaud localization theorem

Abstract

The goal of the present text is to state and prove a generalization of Raynaud localization theorem in the setting of derived geometry. More explicitly, we show that the $\infty$-category of quasi-paracompact and quasi-separated derived $k$-analytic spaces can be realized as a localization of the $\infty$-category of admissible derived formal schemes. We construct a derived rigidification functor generalizing Raynaud rigidification functor. In order to construct the latter we will need to formalize derived formal $\mathcal{O}_k$-adic formal geometry via a structured spaces approach. We prove that $\mathcal{O}_k$-adic Postnikov towers of derived $\mathcal{O}_k$-adic Deligne-Mumford stacks decompose and we relate these to Postnikov towers of derived $k$-analytic spaces. This is possible by a precise comparison between the $\mathcal{O}_k$-adic cotangent complex and the $k$-analytic cotangent complex.
