Title:Local deformation rings and their singularities
Speaker:Vytautas Paškūnas(Universität Duisburg-Essen)
Time:9.21(Monday),10:30-11:30
Venue:Gewu Building 315
Abstract:In this talk I will recall the definition of universal deformation rings of Galois representations of p-adic fields, and review the results on their structure proved with Boeckle, Iyengar and Quast. I will also expose the results obtained by my PhD student Hind Souly in her recent thesis. She shows that the special fibres of irreducible components of local deformation rings are strongly F-regular, and hence F-rational, in many cases, by relating them to the zero fibre of the moment map for representation of quivers.
