Generalized Local Homology Modules of Complexes

The theory of local homology modules was initiated by Matlis in 1974. It is a dual version of the theory of local cohomology modules. Mohammadi and Divaani-Aazar studied the connection between local homology and Gorenstein flat modules by using Gorenstein flat resolutions. In this paper, we introduce generalized local homology modules for complexes and we give several ways for computing these modules by using Gorenstein flat resolutions. We also find a lower bound for vanishing of generalized local homology modules over a commutative Noetherian ring and we give an upper bound for vanishing of these modules over a commutative Noetherian ring possessing a dualizing complex.
