报告摘要：

We shall introduce the homology theory of double complexes over an abelian category and generalize the well known Acyclic Assembly Lemma. This enables us to formalize a method to extend a functor from an abelian category into the complex category of another abelian category to a functor between the two complex categories. This method is essential in our study of the derived categories of Koszul algebras given by locally bounded gradable quivers.
