Abstract
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 [Formula: see text] Gorenstein injective in R-Mod for each [Formula: see text] and any morphism [Formula: see text] is null homotopic whenever E is a DG-injective complex.
