WebThe category of m periodic complexes, for m 2;has independent interest by itself but also it is related to the orbit categories of the bounded derived category. The connection between the orbit categories of the derived categories of an algebra and the m periodic complexes was established by the compression functor.

WebThe problem with derived categories is that most invariants of Xare deter-mined by Db(Coh(X))but they cannot be computed directly from Db(Coh(X)). To understand the derived category, we need to “represent” the derived cate-gory in the same way that differential forms “represent” de Rham cohomology. WebThe stable derived category of a noetherian scheme Theorem 1.4. Let f: X → Y be a morphism between separated noetherian schemes. Denote by Rf∗: D(QcohX) → D(QcohY) the right derived direct image functor and byf! its right adjoint. Then there is an adjoint pair of functorsRˆf∗ and f! making the following diagrams commutative.
