At least the proof in Weibel's book showing that $\mathbf{D}(\mathcal{A})$ is locally small for $\mathcal{A} = R\mathsf{-Mod}$ or $\mathcal{A} = \mathsf{Sheaves}(X)$ uses that ... WebJun 17, 2016 · For example, the derived category of quasi-coherent sheaves (or its various variants) is the category of coefficients for coherent cohomology, just as the derived category of ℓ -adic sheaves is the category of coefficients for ℓ -adic cohomology, or motivic complexes are the coefficients for motivic cohomology.

WebSep 7, 2011 · In the case of derived categories, this requires also the tensor structure. We start with the classical case of the category of coherent sheaves (after Gabriel). We present afterwards a similar approach in the triangulated case, where serious difficulties arise. Finally, we explain how to deduce that a smooth projective variety with ample or ...

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 WebOne might even think of any Ext- nite triangulated category with a Serre functor as being a “non-commutative” variety (or rather, the derived category of sheaves on a hypothetical non-commutative variety). It is useful at times to keep this point view in mind. 1.1. Derived invariants. — Now that we have D(X)it is natural to ask the following:
