“…As a generalization of projective, injective and flat complexes, Enochs et al introduced Gorenstein projective, injective and flat complexes, and developed Gorenstein homological algebra in the category of complexes in [2]. Renyu Zhao and Pengju Ma introduced Gorenstein projective complexes with respect to a cotorsion pair, that is Gorenstein -projective complexes in [5], and investigate stability of Gorenstein -projective complexes.
