Webits adic spectrum, whose points correspond to continuous valuations on A [2]. General adic spaces are obtained by gluing together ringed spaces of the form SpaA. In this series of lectures we present an introduction to the theory with an emphasis on examples. Topics may include: The adic spectrum of a Huber ring The adic closed unit disc D over Q WebThis is a certain space of continuous valuations equipped with pre-sheafs of rings $\mathcal{O}_X$ and $\mathcal{O}^+_X$. We discuss the relevant cases when these pre-sheaves are actually sheaves, allowing to glue adic spectra together to obtain adic spaces.

We define the adic spectrum of a ``Huber pair" ( A, A +) to be Spa ( A, A +) := { ⋅ x ∈ Cont ( A): a x ≤ 1, ∀ a ∈ A + } where Cont ( A) is the space of continuous valuations on A. WebIn this paper we study two types of descent in the category of Berkovich analytic spaces: flat descent and descent with respect to an extension of the ground field. Quite surprisingly, the deepest results in this direction seem to be of the second type, including the descent of properties of being a good analytic space and being a morphism without boundary. dick cake mold
