The connection between the orbit categories of the derived categories of an algebra and the m periodic complexes was established by the compression functor.

WebJan 7, 2000 · Download PDF Abstract: It is becoming increasingly difficult for geometers and even physicists to avoid papers containing phrases like `triangulated category', not to mention derived functors. I will give some motivation for such things from algebraic geometry, and show how the concepts are already familiar from topology. WebDerived categories have since become indispensable also outside of algebraic geometry, for example in the formulation of the theory of D-modules and microlocal analysis. …
Web2 Abelian Categories And Exact Functors As one can guess from the name, an abelian category should be a category that \looks like" Ab. We will attempt to motivate the (somewhat complicated) de nition of an abelian category by examining some nice properties that Ab has as a category. The data of a category consists of its objects and … WebThe machinery needed to define a derived category in full generality tends to obscure the simplicity of the phenomena. We therefore start in section 3 with the example of the …
