Recollements and tilting objects

Abstract: a b s t r a c tWe study connections between recollements of the derived category D(Mod R) of a ring R and tilting theory. We first provide constructions of tilting objects from given recollements, recovering several different results from the literature. Secondly, we show how to construct a recollement from a tilting module of projective dimension one. By Nicolás and Saorín (2009) [31], every recollement of D(Mod R) is associated to a differential graded homological epimorphism λ : R → S. We will focus on the … Show more

“…Furthermore, the question of when we can glue derived equivalencesthat is, tilting objects-comes as a particular setting of the general context of gluing silting. Similar constructions of tilting objects have been discussed in [19] and [2]. In particular, we will show that the construction in [2] is a particular case of the preceding construction.…”

“…In this sense, a recollement of derived categories can be viewed as a natural generalization of a derived equivalence. The relation between tilting theory and recollements of derived categories has been further studied in [1] [6]. The dg version of Rickard's theorem was developed by Keller in [10], and the result of Koenig was generalized to the dg setting by Jørgensen [9] and Nicolás-Saorín [17], where the role of partial tilting complexes is played by compact objects.…”

“…Since t-structures can be glued via a recollement (see [10]) another natural question is the following: given a recollement (1) of triangulated categories and silting sets and in and , is it possible to construct a silting set in corresponding to the glued t-structure? This problem was studied in the context of tilting objects in [4] under some restrictions and in the context of gluing with respect to co-t-structures in [35]. The second goal of this paper is to show that the process of gluing t-structures allows to construct partial silting sets in the central category of a recollement out of partial silting sets in its outer categories.…”
