Derived category of motive
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 WebFor a eld k and commutative ring R, we consider three subcategories of the derived category of motives, DM.kIR/: the category DMT.kIR/of mixed Tate motives, the …

The conjectural theory of mixed motives would be a universal cohomology theory in arithmetic algebraic geometry. The monograph describes the approach to motives via their well-defined realizations. This includes a review of several known cohomology theories. A new absolute cohomology is introduced and studied.
Webcategory. It turned out that derived categories have nice behavior under special birational transformations like blow ups, flips and flops. We describe a semiorthogonal decomposi-tion of the derived category of the blow-up of a smooth variety X in a smooth center Y ⊂ X . It contains one component isomorphic to Db(X) and several components Webunderlying derived category. 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.

WebThe homotopy category K(A) and the derived category D(A), to be introduced in x3, are additive but not abelian categories. Instead, they share an extra structure described by a distinguished collection of exact triangles. Although we are mainly interested in the derived category, we rst consider triangles in the homotopy category.
