Abstract

Let XX be a noetherian scheme with affine diagonal, and let λ:X→X\lambda : \mathcal{X} \to X be a morphism of locally ringed spaces from a qcqs locally strongly noetherian analytic adic space. We prove that an equivalence on coherent sheaves, together with comparison of their cohomology, extends to every proper XX-scheme. As an application, we obtain GAGA for proper schemes over the Fargues--Fontaine curve in equal and mixed characteristic.
