Title	Deformations and the homotopy Lie algebra of a local ring
Abstract	I discuss joint work with Briggs, Grifo, and Pollitz, in which we investigate a question due to Avramov: Does every central element of degree two in the homotopy Lie algebra of a local ring come from an embedded deformation? I’ll define the terms appearing in this question and answer it. (Spoiler alert: No)
