Classifying -structures via ICE-closed subcategories and a lattice of torsion classes
A Sakai - arXiv preprint arXiv:2307.11347, 2023 - arxiv.org
In a triangulated category equipped with a $ t $-structure, we investigate a relation between
ICE-closed (= Image-Cokernel-Extension-closed) subcategories of the heart of the $ t …

[HTML][HTML] Silting theory in triangulated categories with coproducts
We introduce the notion of noncompact (partial) silting and (partial) tilting sets and objects in
any triangulated category D with arbitrary (set-indexed) coproducts. We show that …

Tilting Modules and Tilting Torsion Pairs: Filtrations Induced by Tilting Modules
F Mattiello, S Pavon, A Tonolo - … : Graz, Austria, February 19-23, 2018, 2020 - Springer
Tilting modules, generalising the notion of progenerator, furnish equivalences between
pieces of module categories. This paper is dedicated to study how much these pieces say …

Ideal cotorsion theories in triangulated categories
We study ideal cotorsion pairs associated to weak proper classes of triangles in extension

[HTML][HTML] Quasi-abelian hearts of twin cotorsion pairs on triangulated categories
A Shah - Journal of Algebra, 2019 - Elsevier
We prove that, under a mild assumption, the heart H‾ of a twin cotorsion pair ((S, T),(U, V))
on a triangulated category C is a quasi-abelian category. If C is also Krull-Schmidt and T= U …
