Deligne groupoid revisited

Algebraic Topology 2015-05-26 v4 Differential Geometry

Abstract

We show that for a differential graded Lie algebra g\mathfrak{g} whose components vanish in degrees below -1 the nerve of the Deligne 2-groupoid is homotopy equivalent to the simplicial set of g\mathfrak{g}-valued differential forms introduced by V.Hinich.
