Torsion pairs via the Ziegler spectrum
Lidia Angeleri Hügel, Rosanna Laking, Francesco Sentieri
We establish a bijection between torsion pairs in the category of finite-dimensional modules over a finite-dimensional algebra A and pairs (Z, I) formed by a closed rigid set Z in…
Partial silting objects and smashing subcategories
Lidia Angeleri Hügel, Frederik Marks, Jorge Vitória
We study smashing subcategories of a triangulated category with coproducts via silting theory. Our main result states that for derived categories of dg modules over a non-positive…
Tilting modules and universal localization
Lidia Angeleri Hügel, Maria Archetti
We show that every tilting module of projective dimension one over a ring R is associated in a natural way to the universal localization (in the sense of Schofield) of R at a set o…
Tilting modules arising from ring epimorphisms
Lidia Angeleri Hügel, Javier Sánchez
Given a ring R, we investigate tilting modules of the form S \oplus S/R for some injective ring epimorphism R \to S. In particular, we are interested in tilting modules arising fro…
Baer and Mittag-Leffler modules over tame hereditary algebras
Lidia Angeleri-Hugel, Dolors Herbera, Jan Trlifaj
We develop a structure theory for two classes of infinite dimensional modules over tame hereditary algebras: the Baer modules, and the Mittag-Leffler ones.
