Mittagsseminar: Prof. Dr. Vytautas Paskunas (Universität Essen): On local Galois deformation rings
Tuesday, 30.11.2021 10:15 im Raum SRZ 216/217
We show that framed deformation rings of mod p representations of the absolute Galois group of a p-adic local field are complete intersections of expected dimension. We determine their irreducible components and show that they and their special fibres are normal and complete intersection. As an application we prove density results of loci with prescribed p-adic Hodge theoretic properties.
