Title: The derived category of a DG-algebra


Abstract:  We will describe the derived category of a DG-algebra as a triangulated category. It arises as the homotopy category of a model structure on DG-modules. We will tackle the question: When do two DG-algebras have equivalent derived categories? In stark contrast to the case of rings, for DG-algebras, the derived category does not determine the homotopy theory of DG-modules.
