Moduli problems for operadic algebras

Abstract

A theorem of Pridham and Lurie provides an equivalence between formal moduli problems and Lie algebras in characteristic zero. We prove a generalization of this correspondence, relating formal moduli problems parametrized by algebras over a Koszul operad to algebras over its Koszul dual operad. In particular, when the Lie algebra associated to a deformation problem is induced from a pre-Lie structure, it corresponds to a permutative formal moduli problem. As another example, we obtain a correspondence between operadic formal moduli problems and augmented operads.
