The model structure on simplicial algebras for simplicial Lie algebras.
For some field, write for the category of Lie algebras over , and write
for the category of simplicial objects in that category, naturally regarded as a simplicial category. Say a morphism in that category is a weak equivalence or fibration, if its underlying morphism of simplicial sets is a weak equivalence or fibration, respectively, in the classical model structure on simplicial sets. Write for the category equipped with these classes of morphism.
The category from def. is a simplicial model category.
Since Lie algebras are algebras over a Lawvere theory, this is a special case of (Reedy 74, theorem I) discussed at model structure on simplicial algebras. Without the simplicial enrichment and on reduced simplicial Lie algebras this model structure is a special case of (Quillen 67, II.4 theorem 4) and also left as an exercise for the reader in (Quillen 69, below theorem 4.7).
Let be a simplicial Lie algebra. Then the normalized chains complex of the underlying simplicial abelian group becomes a dg-Lie algebra by equipping it with the Lie bracket given by the following composite morphisms
where the first morphism is the Eilenberg-Zilber map.
This construction extends to a functor
from simplical Lie algebras to dg-Lie algebras.
The functor from simplicial Lie algebras to dg-Lie algebras from def. has a left adjoint
This is (Quillen 69, prop. 4.4).
With respect to the projective model structure on simplicial Lie algebras from prop. and the projective model structure on dg-Lie algebras (this prop.) the adjunction from prop. is a Quillen adjunction
By the standard Dold-Kan correspondence preserves fibrations and weak equivalences (this prop., Schwede-Shipley 02, section 4.1, p.17).
The adjunction between homotopy categories of the derived functors of the Quillen adjunction in prop.
restricts on connected simplicial algebras and connected dg-Lie algebras (meaning: having the trivial Lie algebra in degree 0) to an equivalence of categories:
(Quillen 76, section II.4, see p. 224 (20 of 92), see also figure 2 on p. 211 (8 of 92))
