WebbDERIVED CATEGORIES AND TILTING 5 Lemma. If U⊂HAis left or right cofinal, then the essential image of Uin DA is equivalent to the localization of Uat the class of quasi-isomorphisms s : U →U′ with U,U′ ∈U. For example, the category H−(A) of complexes U with Un = 0 for all n ≫0 is easily seen to be left cofinal in HA.
