摘 要:
It is shown that the relative Auslander-Buchweitz context on a triangulated category T coincides with the notion of co-t-structure on certain triangulatedsubcategory of T. In the Krull-Schmidt case, it is stablished a bijective correspondence between co-t-structures and cosuspended, precovering subcategories. Finally, it is given a characterization of bounded co-t-structures in terms of relative homological algebra.
