Hence, it is crucial to understand dg categories up to derived Morita equivalence. The following result is central in this direction. Theorem 3.1. ([42, 48]) The category dgcatcarries a (cofibrantly generated) Quillen model structure3 whose weak equivalences are the derived Morita equiva-lences.

WebWe embed the derived category of Deligne 1-motives over a perfect field into the étale version of Voevodsky’s triangulated category of geometric motives, after inverting the exponential characteristic. We then show tha… WebMotivation: Derived categories as higher invariants. Let k be a field and A a k-algebra (associative, with 1). We are especially interested in the case where A is a non commutative algebra. In order to study A, one often looks at various invariants associated with A, for example its Grothendieck group K

WebSep 28, 2024 · 2. I can't answer the whole question, but one motivation for derived categories is "Verdier duality" for (complexes of) sheaves. For regular enough spaces the exceptional direct image functor f! may have a right adjoint f!, but in general this right adjoint (the exceptional inverse image) only exists at the level of the derived category as the ...

WebWe show that the subcategory of mixed Tate motives in Voevodsky’s derived category of motives is not closed under infinite products. In fact, the infinite product $\prod _{n=1}^{\infty }\mathbf{Q}(0)$ is not mixed Tate. More generally, the inclusions of several subcategories of motives do not have left or right adjoints.

There are essentially no limits in the derived category, whether the diagram factors through chain complexes or not. For instance, any monomorphism in any triangulated category must be split.
