Abstract

In this article, we characterize some rings in terms of the DG-projective, injec-tive and flat complexes. We also give some connections between DG-injective complexes and DG-flat complexes and prove that under some additional conditions, every complex of left ii-modules has a DG-flat preenvelope.
