Derived category math
WebThe derived category for A can be thought of as a category obtained from Ch(A ) by having quasi-isomorphisms be actual isomorphisms. oT do this, we localize ( = invert) quasi-isomorphisms. De nition 1.4. Let A be an additive category and let S be a class of morphisms in A closed under composition. Let A S be an additive category and let L: A !A Webabelian category A, we construct the associated derived category D(A), which objects are complexes of objects in Aand arrows are homotopy classes of morphisms of complexes to which we added “inverses” of quasi-isomorphisms. This new category admits a structure of triangulated category, and has many properties that we briefly study.
