Alonso Tarrío, Leovigildo; Jeremías López, Ana; Souto Salorio, María José Localization in categories of complexes and unbounded resolutions. (English) Zbl 0948.18008 Can. J. Math. 52, No. 2, 225-247 (2000). Authors’ abstract: In this paper we show that for a Grothendieck category \({\mathcal A}\) and a complex \(E\) in \(\mathbb{C}({\mathcal A})\) there is an associated localization endofunctor \(\ell\) in \(\mathbb{D} ({\mathcal A})\). This means that \(\ell\) is idempotent (in a natural way) and that the objects that go to 0 by \(\ell\) are those of the smallest localizing (= triangulated and stable for coproducts) subcategory of \(\mathbb{D} ({\mathcal A})\) that contains \(E\). As applications, we construct \(K\)-injective resolutions for complexes of objects of \({\mathcal A}\) and derive Brown representability for \(\mathbb{D}({\mathcal A})\) from the known result for \(\mathbb{D}(R\)-mod), where \(R\) is a ring with unit.
