Derived Galois deformation rings

Abstract: Recently Galatius and Venkatesh showed that the graded homotopy ring of the derived Galois deformation ring should be isomorphic to a certain Tor-algebra arising from the Taylor-Wiles method. In this talk, I will explain some refinements when the group has a non-trivial center and there are formally smooth local deformation conditions.
