摘要

The notion of DG-Gorenstein injective complexes is studied in this article.It is shown that a complex G is DG-Gorenstein injective if and only if G is exact with Zn (G) Gorenstein injective in R-Mod for each n ∈ Z and any morphism f: E → G is null homotopic whenever E is a DG-injective complex.
