WebThe crucial point of derived categories is that D ( 𝒞) knows how to subtract or annihilate objects of 𝒞. 𝒞, being abelian, is an additive category, but need not have a notion of subtraction. In order to get that, one needs to make use of the translation functor. (6) T: D ( 𝒞) → D ( 𝒞) which shifts all the indices n of the ...

WebMar 27, 2006 · I’ll briefly recall the derived category, and give some examples of equivalences of derived categories ( a.k.a Fourier-Mukai transforms ) as well as explaining how such examples are constructed. Examples relate to moduli of bundles, the McKay correspondence and birational geometry of threefolds. Web1. Derived categories The derived category D(A) of an abelian category Aprovides a framework for studying the homological properties of A. The main idea is to replace objects in A by complexes, and to invert maps between complexes if they induce an isomorphism in cohomology. The actual construction of the derived category proceeds in several
WebGiven A an abelian category, we denote by D.A/the derived category of A and we denote by Da.A/the full subcategory of objects with cohomology vanishing in degrees >a. Let Abe a differential graded (=dg) algebra. We denote by D.A/the derived category of dg A-modules and by A-perf the category of perfect complexes, i.e.,the
