Abstract

The derived Maurer-Cartan locus MC(L)\text{MC}^\bullet(L) is a functor from differential graded Lie algebras to cosimplicial schemes. If L is differential graded Lie algebra, let L+L_+ be the truncation of LL in positive degrees i>0i>0. We prove that the differential graded algebra of functions on the cosimplicial scheme MC(L)\text{MC}^\bullet(L) is quasi-isomorphic to the Chevalley-Eilenberg complex of L+L_+.
