Learning objectives
The course consists in an introduction to non-archimedean arithmetic geometry using the language of adic spaces, formal schemes and condensed rings. We will provide some fundamental examples such as Tate's analytic varieties, Scholze's perfectoid spaces and the Fargues-Fontaine curve. We will discuss applications of this formalism to the study of p-adic cohomology theories.
Expected learning outcomes
By the end of the course, students will be able to handle the language and techniques of modern non-archimedean geometry, which are the foundations of the recent developments in p-adic Hodge theory.
Single course

This course can be attended as a single course.

Introduction to non-archimedean analytic geometry and its applications to arithmetic geometry.

- Basic definitinons of Raybaud's theory via formal schemes and blow-ups, specialization maps.
- de Rham cohomology for rigid varieties: dagger structures, analytic spaces à la Clausen-Scholze, homotopy theory.
- Rigid cohomology.
