Abstract

Let RR be a commutative noetherian ring. Denote by modR\operatorname{mod}R the category of finitely generated RR-modules, by Db(R)\operatorname{D^b}(R) the bounded derived category of modR\operatorname{mod}R, and by Dsg(R)\operatorname{D_{sg}}(R) the singularity category of RR. The main result of this paper provides, when RR is a complete intersection, a complete classification of the preaisles of Db(R)\operatorname{D^b}(R) containing RR and closed under direct summands, which includes as restrictions the classification of thick subcategories of Dsg(R)\operatorname{D_{sg}}(R) due to Stevenson, and the classification of resolving subcategories of modR\operatorname{mod}R due to Dao and Takahashi.
