Silting objects, simple-minded collections, tt-structures and co-tt-structures for finite-dimensional algebras

preprint2013arXivOpen access

Abstract

Bijective correspondences are established between (1) silting objects, (2) simple-minded collections, (3) bounded tt-structures with length heart and (4) bounded co-tt-structures. These correspondences are shown to commute with mutations. The results are valid for finite-dimensional algebras. A concrete example is given to illustrate how these correspondences help to compute the space of Bridgeland's stability conditions.
