DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGA-AGAA/6/
 ">Derived Galois deformation rings</a>\nby Yichang Cai (Université Sorbon
 ne Paris Nord) as part of Séminaire de géométrie arithmétique et motiv
 ique (Paris Nord)\n\n\nAbstract\nRecently Galatius and Venkatesh showed th
 at the graded homotopy ring of the derived Galois deformation ring should 
 be isomorphic to a certain Tor-algebra arising from the Taylor-Wiles metho
 d. In this talk\, I will explain some refinements when the group has a non
 -trivial center and there are formally smooth local deformation conditions
