DESCRIPTION:Speakers: Sonja Maria Farr (MPIM)\n\nMPI-Oberseminar\nA formal
  moduli problem is a space modeling the formal neighborhood of a point in 
 a moduli stack. By the Lurie-Pridham correspondence\, every formal moduli 
 problem in characteristic 0 is controlled by a dg Lie algebra. Calaque-Cam
 pos-Nuiten proved an operadic version of this correspondence\, showing tha
 t formal moduli problems parametrized by algebras over a sufficiently nice
  dg operad correspond to algebras over the Koszul dual operad. A basic exa
 mple is the deformation theory of an 𝐸_n -algebra . By a result of J. F
 rancis\, this is a 𝐸_{n+1} -formal moduli problem controlled by the E_n
 -Hochschild cohomology of 𝐴\, recovering the familiar principle that Ho
 chschild cohomology controls deformations. In this talk I will explain a r
 ecent result of mine extending this picture to dg operads\, proving that t
 he derived center of an algebra controls its operadic deformation theory\n
