On local Galois deformation rings

Julian Quast (Universität Duisburg-Essen)
In joint work with Vytautas Paškūnas, we show that the universal framed
deformation ring of an arbitrary mod p representation of the absolute
Galois group of a p-adic local field valued in a possibly disconnected
reductive group G is flat, local complete intersection and of the
expected dimension. In particular, any such mod p representation has a
lift to characteristic 0. The work extends results of Böckle, Iyengar
and Paškūnas in the case G=GL_n. We give an overview of the proof of
this main result.
