Mittagsseminar zur Arithmetik: Nataniel Marquis (Münster): Plectic Fontaine equivalence

Tuesday, 20.01.2026 10:15 im Raum SRZ 216/217

Mathematik und Informatik

In the previous talk, Fontaine equivalence was found to be a central tool for p-adic local Langlands correspondance for GL2(Qp). It describes the involved category of Galois representations in terms of another semilinear algebra category called étale (?,?)-modules. We will first explain why the case of GL2(K) bends towards the apparition of what may be called plectic (?,?)-modules using the work of Breuil-Herzig-Hu-Morra-Schraen. Then, we aim to give an overview of a Fontaine equivalence in this situation, as obtained in my thesis.
