Hausdorff School on the Emerton-Gee stack and related topics

Dates: September 9 - 13, 2019

Venue: Lipschitz-Saal (Endenicher Allee 60, Bonn)

Organizers: Johannes Anschütz, Arthur-César Le Bras and Andreas Mihatsch



The Emerton-Gee stack is an object whose geometric properties reflect deep results about p-adic Galois representations of local fields. It is constructed using (phi,Gamma)-modules and Breuil-Kisin-Fargues modules with coefficients, and the study of its geometry is intimately connected with important problems in the p-adic Langlands program, including generalizations of Serre's modularity conjecture and the Breuil-Mezard conjecture. The goal of the Hausdorff school is to give a detailed and example-based introduction, accessible to PhD students and post-docs in the field, to the Emerton-Gee stack: its construction, its properties and some of its applications. Related topics, such as the relation between Breuil-Kisin modules and p-divisible groups, or the theory of (phi,Gamma)-modules may be explored as well.
