Time and Place

Wednesday, 14-16h, kleiner Hörsaal
First Lecture: Wednesday 16.10.2019.

Content of the course

We will introduce the fundamental curve of p-adic Hodge theory which was discovered by Fargues and Fontaine. It offers a geometric perspective on p-adic Hodge theory and is at the core of Fargues' program to geometrize the local Langlands correspondence. We will focus on the schematic version of the Fargues-Fontaine curve and prove some of its basic properties, e.g., that it is a Dedekind scheme. Using the classification of vector bundles on it we will derive the classical theorem that "weakly admissible" implies "admissible".

Prerequisites

Knowledge of valuations, p-adic fields and basic scheme theory.
