Webbecome true in the language of derived categories and functors. 2 Outline of the Chapter The machinery needed to deflne a derived category in full generality tends to obscure the simplicity of the phenomena. We therefore start in section 3 with the example of the derived category of a module category. WebJun 17, 2016 · $\begingroup$ This might be overly pedantic, but to get the right $\infty$-category of quasicoherent sheaves I think you need to take the limit of the cosimplicial diagram that takes all the iterated intersections into account, rather than just an equalizer. (This is a general theme in passing from 1-categories to $\infty$-categories. In a sense …

WebOrlov studied the derived category and the category of singularities of such an algebras in great detail in [21], and much of the technique of the proof of Theorem 1.1 derives from that paper. In the context of equivariant K ahler geometry, one can consider Theorem 1.1 as a categori- cation of Kirwan surjectivity.
