. 给出了复合体和双模的内射分解的新构造。将此构造应用于Noetherian环的内射解析,我们构造了一个(cid:6)-嵌入共发生器,用于射影维数(cid:20) n的模类。此外,对于一个Noetherian射影k -代数R,我们证明了R满足(cid:12)的Auslander条件当且仅当每个R -模M的维数(cid:13)等于或大于单射壳E(M)的维数(cid:13)。
. 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 ).
