Title: DG Lie algebras and coalgebras in rational homotopy theory

Abstract:

A classic theorem of Quillen established an equivalence of homotopy theory between (certain) DG Lie algebras and DG coalgebras. Both are models for (simply-connected) rational homotopy theory. A generalization of Quillen's result by Hinich provided a link with deformation theory.
