NOTES ON DERIVED CATEGORIES AND DERIVED FUNCTORS

WebThe crucial point of derived categories is that D ( 𝒞) knows how to subtract or annihilate objects of 𝒞. 𝒞, being abelian, is an additive category, but need not have a notion of subtraction. In order to get that, one needs to make use of the translation functor. (6) T: D ( 𝒞) → D ( 𝒞) which shifts all the indices n of the ... 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.

WebDescription. The goal of the school is to give an introduction to basic techniques for working with derived categories, with an emphasis on the derived categories of coherent sheaves on algebraic varieties.

WebThe derived category is a natural framework to define and study derived functors. In the following, let F: A → B be a functor of abelian categories. There are two dual concepts: right derived functors come from left exact functors and are calculated via injective resolutions simpsons toys archiveWebGiven A an abelian category, we denote by D.A/the derived category of A and we denote by Da.A/the full subcategory of objects with cohomology vanishing in degrees >a.
