X-INJECTIVE AND X-PROJECTIVE COMPLEXES

Let X be a class of R-modules. In this paper, we investi- gate X-injective (projective) and DG-X-injective (projective) complexes which are generalizations of injective (projective) and DG-injective (projective) complexes. We prove that some known results can be extended to the class of X-injective (projective) and DG-X-injective (projective) complexes for this general settings.
