Triangulated categories with simple-minded collections

アブストラクト

A triangulated category admitting a simple-minded collection is equivalnet to the derived category of a positive dg algebra in the sense of Keller and Nicolás. We develop a general theory for such categories. Furthermore, by analyzing the Koszul duality between positive dg algebras and non-positive dg algebras, we generalize the bijection between silting objects and simple-minded collections established by Koenig and Yang.
