Relative tilting theory in abelian categories I: Auslander-Buchweitz-Reiten approximations theory in subcategories and cotorsion pairs

AA Monroy, OM Hernández - arXiv preprint arXiv:2104.11361, 2021 - arxiv.org
In this paper we introduce a special kind of relative (co) resolutions associated to a pair of
classes of objects in an abelian category $\mathcal {C}. $ We will see that, by studying these …

Relative tilting theory in abelian categories II: --tilting theory

AA Monroy, OM Hernandez - arXiv preprint arXiv:2112.14873, 2021 - arxiv.org
We introduce a relative tilting theory in abelian categories and show that this work offers a
unified framework of different previous notions of tilting, ranging from Auslander-Solberg …

Suppose that $\mathcal {A} $ is an abelian category whose derived category $\mathcal
{D}(\mathcal {A}) $ has $ Hom $ sets and arbitrary (small) coproducts, let $ T $ be a (not …

Ideal cotorsion theories in triangulated categories

S Breaz, GC Modoi - Journal of Algebra, 2021 - Elsevier
We study ideal cotorsion pairs associated to almost exact structures in extension closed
subcategories of triangulated categories. This approach allows us to extend the recent ideal …

Ideal approximation in -exangulated categories

Y Wang, J Wei - arXiv e-prints, 2022 - ui.adsabs.harvard.edu
In this paper, we study the ideal approximation theory associated to almost $ n $-exact
structures in the $ n $-exangulated category. The notions of $ n $-ideal cotorsion pairs and …

Equivalences from tilting theory and commutative algebra from the adjoint functor point of view

O Celikbas, H Holm - arXiv preprint arXiv:1703.06685, 2017 - arxiv.org
We give a category theoretic approach to several known equivalences from (classic) tilting
theory and commutative algebra. Furthermore, we apply our main results to establish a …

On Auslander's formula and cohereditary torsion pairs

A Banerjee - Communications in Contemporary Mathematics, 2018 - World Scientific
For a small abelian category C, Auslander's formula allows us to express C as a quotient of
the category mod− C of coherent functors on C. We consider an abelian category with the …

Ideal cotorsion theories in triangulated categories

S Breaz, GC Modoi - arXiv preprint arXiv:1501.06810, 2015 - arxiv.org
We study ideal cotorsion pairs associated to weak proper classes of triangles in extension
closed subcategories of triangulated categories. This approach allows us to extend the …

𝜏-tilting theory in abelian categories

Y Liu, P Zhou - Proceedings of the American Mathematical Society, 2022 - ams.org
Let $\mathcal {A} $ be a Hom-finite abelian category with enough projectives. In this note,
we show that any covariantly finite $\tau $-rigid subcategory is contained in a support $\tau …
