On chain maps inducing isomorphisms in homology
Let A be an abelian category, I the full subcategory of A consisting of injective objects of A, and K(A) the category whose objects are cochain complexes of elements of A, and whose morphisms are homotopy classes of cochain maps. In (5), lemma 4.6., p. 42, R. Hartshorne has proved that, under certa...
