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 kk-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 Ok\mathcal{O}_k-adic formal geometry via a structured spaces approach. We prove that Ok\mathcal{O}_k-adic Postnikov towers of derived Ok\mathcal{O}_k-adic Deligne-Mumford stacks decompose and we relate these to Postnikov towers of derived kk-analytic spaces. This is possible by a precise comparison between the Ok\mathcal{O}_k-adic cotangent complex and the kk-analytic cotangent complex.
