. We give new construction of injective resolutions of complexes and bimodules. Applying this construction to an injective resolution of a Noetherian ring, we construct a (cid:6)-embedding cogenerator for the category of modules of projective dimension (cid:20) n . Moreover, for a Noetherian projective k -algebra R , we show that R satis(cid:12)es the Auslander condition if and only if the (cid:13)at dimension of every R -module M is equal to or larger than the one of the injective hull E( M ).
