On derived equivalence classification of gentle two-cycle algebras [PDF]
, 2007 We classify, up to derived (equivalently, tilting-cotilting) equivalence all nondegenerate gentle two-cycle algebras.

Cotorsion pairs, torsion pairs, and
Journal of Pure and Applied Algebra, 2010 Let \(R\) be a ring with identity element, and let \({\mathcal M}od\)-\(R\) be the category of unital right \(R\)-modules. The aim of this paper is to investigate cotorsion pairs and torsion pairs induced by a cotilting right \(R\)-module, briefly called cotilting cotorsion pairs and cotilting torsion pairs, respectively.

Projective-injective modules, Serre functors and symmetric algebras [PDF]
, 2005 We describe Serre functors for (generalisations of) the category O associated with a semi-simple complex Lie algebra. In our approach, projective-injective modules play an important role.

, 2008 For an abelian category $A$ equipped with a torsion pair, we give an explicit description for the abelian category $B$ introduced by Happel-Reiten-Smalo, and also for the category of chain complexes $Ch(B)$ and the derived category $D(B)$ of $B$. We also

Communications in Algebra, 2000 Over an arbitrary ring, we consider cotilting modules endowed with some finiteness conditions. We show that they correspond to pairs of dualities between certain cat-egories consisting of finitely presented modules. This extends the Cotilting Theorem proved by Colby for the noetherian case.
