- Derived category - Wikipedia
Despite the level of abstraction, derived categories became accepted over the following decades, especially as a convenient setting for sheaf cohomology Perhaps the biggest advance was the formulation of the Riemann–Hilbert correspondence in dimensions greater than 1 in derived terms, around 1980
- DERIVED CATEGORIES Contents - Columbia University
1 Introduction in triangulated categories Next, we prove that the homotopy category of complexes in an additive category is a triangulated category Once this is done we define the derived category of an abelian category as the localization of the homotopy category with re pect to quasi-isomorphisms A good reference is Ve dier’s thesis [Ver96]
- The Derived Category - MIT Mathematics
Therefore we could have defined the derived category to be the localization Q~lCh(A) However, in order to prove that Q~lCh(A) exists we must first prove that Q~lK(A) exists, by giving an explicit description of the mor-phisms

In fact, they are precisely the adjoints of the inclusions of categories: τ≤N is the right adjoint to the inclusion D≤N ,→ D, and τ≥N is the left adjoint to the inclusion D≥N ,→ D
- Some remarks on L-equivalence for cubic fourfolds and hyper-Kähler . . .
Indeed, cubic fourfolds are the archetypal example of Fano varieties of K3 type (see [17] for the formal definition and a survey on the subject) From the points of view of Hodge theory and derived categories, these manifolds share many properties with K3 surfaces and more in general with hyper-Kähler manifolds
- Derived categories and algebraic geometry
Inspired by work on the stable homotopy category (description of the chromatic tower), Hopkins and Neeman [Ho, Neel] have given a classification of thick subcategories of the category of perfect complexes over an affine variety
- Localization of Categories (Chapter 6) - Derived Categories
In this section we take a close look at localization of categories Let K be an abstract category (i e without any extra structure), and let S ⊆ K be a multiplicatively closed set of morphisms
- Derived and Triangulated Categories - Uni Bielefeld
Note that the category R–Proj isn’t abelian, it is only an exact category D(R–proj) has for objects all cochain complexes of finitely generated projective left R-modules Db(R–proj) has for objects all bounded cochain complexes of finitely generated, projective left R-modules
- Lectures on Derived Categories Dragan Mili ci c - University of Utah
2 Localization of additive categories 2 1 Localization of an additive category Assume now that A is an ad-ditive category and that S is a localizing class of morphisms in A
- Derived Categories of Coherent Sheaves
First, we investigate the behaviour of derived categories of coherent sheaves when the underlying variety is subject to birational transformations such as flips, flops and contractions, which are the common operations applied in the minimal model program
