Abstract

Let R be a commutative noetherian ring.Denote by mod R the category of finitely generated R-modules, by D b (R) the bounded derived category of mod R, and by D sg (R) the singularity category of R. The main result of this paper provides, when R is a complete intersection, a complete classification of the preaisles of D b (R) containing R and closed under direct summands, which includes as restrictions the classification of thick subcategories of D sg (R) due to Stevenson, and the classification of resolving subcategories of mod R due to Dao and Takahashi.1.
