On large and small torsion pairs
F Sentieri - 2022 - iris.unitn.it
Torsion pairs were introduced by Dickson in 1966 as a generalization of the concept of
torsion abelian group to arbitrary abelian categories. Using torsion pairs, we can divide …

[HTML][HTML] On t-structures and torsion theories induced by compact objects
M Hoshino, Y Kato, JI Miyachi - Journal of Pure and Applied Algebra, 2002 - Elsevier
First, we show that a compact object C in a triangulated category, which satisfies suitable
conditions, induces a t-structure. Second, in an abelian category we show that a complex P …

[PDF][PDF] Reading course: Torsion pairs in abelian categories
R Laking, J Vitoria - math.unipd.it
Aim: A torsion pair in an abelian category is a decomposition of it into two parts: a torsion
and a torsionfree part. It turns out that both the study of individual torsion pairs and the study …

N-Quasi-Abelian Categories vs N-Tilting Torsion Pairs
L Fiorot - Documenta Mathematica, 2021 - content.ems.press
It is a well established fact that the notions of quasi-abelian categories and tilting torsion
pairs are equivalent. This equivalence fits in a wider picture including tilting pairs of t …

Torsion theories and Auslander-Reiten sequences
P Ng - 2011 - theses.ncl.ac.uk
Chapter 0 gives a gentle background to the thesis. It begins with some general notions and
concepts from homological algebra. For example, not only are the notions of universal …

Tilting modules and tilting torsion theories
R Colpi, J Trlifaj - Journal of Algebra, 1995 - Elsevier
We generalize basic results about classical tilting modules and partial tilting modules to the
infinite dimensional case, over an arbitrary ring R. The methods employed combine classical …
