Master seminar p-adic Galois representations
Date & time: Tuesday 14-16
First session: November 3, 2020
Place: online via Zoom (see moodle)
Moodle: There is an electronic classroom for the seminar on the moodle platform. Read backward, the enrolment key needed to subscribe is
Prerequisites: You need a strong background in algebra and some general structure theory of nonarchimedean fields. For a few talks some basic knowledge of algebraic geometry might be helpful
Requirements: According to the regulations of our master program each participant is supposed to give two talks.
Content: One of the main objectives of algebraic number theory is to understand the absolute Galois group of a local or a global field. We will focus on nonarchimedean local fields of residue characteristic p and study their absolute Galois groups through so-called p-adic representations, i.e. continuous linear actions on finite dimensional p-adic vector spaces. In this setting, large parts of the theory go back to Jean-Marc Fontaine and his school.
The topics covered include examples from algebraic geometry, étale phi-modules, the tilting equivalence for perfectoid fields, étale (phi,Gamma)-modules, the formalism of period rings, Hodge-Tate representations, de Rham representations, crystalline representations, semistable representations, filtered isocrystals and the main theorems of p-adic Hodge theory.
Registration: If you wish to give a talk please enrol in the electronic class room and send me an email. Please indicate possible preferences concerning the talks. The final schedule will be published on moodle in September.
