Theorems
The category of dg-modules over a dg-algebra, or more generally a dg-category, admits dg-model structures which present the derived dg-category.
In the case of dg-algebras in an abelian category , dg-modules are the same as modules over algebras over the associative operad in . These admit model structures as described in model structure on modules over an algebra over an operad, transferred from the model structures on chain complexes in .
More generally there are model structures on dg-modules over a dg-category, analogous to model structures on simplicial presheaves.
(projective model structure)
There is a cofibrantly generated model structure on the category of dg-modules, called the projective model structure, where
the weak equivalences are object-wise quasi-isomorphisms of chain complexes,
the fibrations are object-wise epimorphisms.
Moreover, this is a dg-model structure.
(injective model structure)
There is a model structure on the category of dg-modules, called the injective model structure, where
the weak equivalences are object-wise quasi-isomorphisms of chain complexes,
and the cofibrations are object-wise monomorphisms.
See (Toën 04, section 3) and (Keller 06, theorem 3.2).
These model structures present the derived dg-category.
