Outline of Final Research Achievements

We introduce the notion of complexes of finite Gorenstein projective dimension and show that a derived equivalence induces an equivalence between the full triangulated subcategories consisting of complexes of finite Gorenstein projective dimension
provided that the equivalence satisfies a certain condition.
