A model category structure on the category of dg-coalgebras.
Let be a field of characteristic 0.
There is a pair of adjoint functors
between the category of dg-Lie algebras (on unbounded chain complexes) and that of dg cocommutative coalgebras, where the right adjoint sends a dg-Lie algebra to its “Chevalley-Eilenberg coalgebra”, whose underlying coalgebra is the free graded co-commutative coalgebra on and whose differential is given on the tensor product of two generators by the Lie bracket .
This is (Hinich98, theorem, 3.1). More details on this are in the relevant sections at model structure for L-infinity algebras.
Relation to the model structure on dg-Lie algebras
(Hinich98, lemma 5.3.2)
Hence is a Quillen adjunction to the model structure on dg-algebras.
This is (Hinich98, theore, 3.2).
