nLab adic space




Adic spaces are the basic objects in Huber’s approach to non-archimedean analytic geometry. They are built by gluing valuation spectra? of a certain class of topological rings. Unlike Berkovich analytic spectra the points of adic spaces correspond to valuations of arbitrary rank, not only rank one. If a Berkovich space is corresponding to a separated rigid analytic space then it can be obtained as the largest Hausdorff quotient of the corresponding adic space.

The framework of adic spaces are used to build perfectoid spaces out of perfectoid rings.
