In this paper, we investi- gate χ-injective (projective) and DG-χ-injective (projective) complexes which are generalizations of injective (projective) and DG-injective (pro- jective) complexes. We prove that some known results can be extended to the class of χ-injective (projective) and DG-χ-injective (projective) complexes for this general settings. © 2016 Iranian Mathematical Society.eninfo:eu-repo/semantics/closedAccessInjective (Projective) complexPrecoverPreenvelopeArticle425122112352-s2.0-84994633359Q3
