Deformations and the homotopy Lie algebra
Abstract: A semi-classical question of Avramov asks whether embedded deformations of a local ring correspond exactly to central elements in the homotopy Lie algebra of the ring. In this talk, I will explain the question and some recent insights. The latter is based on joint work with Briggs, Grifo, and Walker.
