Localizing and colocalizing subcategories on schemes
Abstract
A full triangulated subcategory of triangulated category is \emph{localizing} if it is stable for coproducts. If, further, is -triangulated, we say that is -ideal if for all and all . Analogously, a full triangulated subcategory is \emph{colocalizing} if it is stable for products. If, further, is \emph{closed}, \textit{i.e.} -triangulated with internal homs (denoted ), we say that is -coideal if for all and all . For a point generated concentrated scheme , we prove that all -ideal localizing subcategories of are classified by the subsets of . As a consequence, we prove that for -coideal colocalizing subcategories of the same holds. Moreover, every such colocalizing subcategory is of the form , where is a -ideal localizing subcategory.
