Abstract
Relations between Gorenstein derived categories, Gorenstein defect categories and Gorenstein stable categories are established. Using these, the Gorensteinness of an algebra and invariants with respect to recollements of the bounded Gorenstein derived category of are investigated. Specifically, the Gorensteinness of is characterized in three ways: the existence of Auslander-Reiten triangles in ; recollements of ; and also Gorenstein derived equivalences. It is shown that the finiteness of Cohen-Macaulay type and of finitistic dimension are invariant with respect to the recollements of .
