Abstract
In the present paper, we investigate the universal PBW basis and HN system for the derived Hall algebra of a triangulated category satisfying some finiteness conditions. Furthermore, we study the related stability conditions on the module category of the path algebra A of an acyclic quiver and on the bounded derived category of . Moreover, we investigate the relation between the Ringel-Hall algebra and the HN system of A defined by Reineke.
