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

P Nicolás, M Saorín, A Zvonareva - Journal of Pure and Applied Algebra, 2019 - Elsevier
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 …

[HTML][HTML] T-structures on unbounded twisted complexes

F Genovese - Mathematische Zeitschrift, 2023 - Springer
This paper is a sequel to T-structures and twisted complexes on derived injectives by the
same author with W. Lowen and M. Van den Bergh. We define a dg-category of unbounded …

TQFT with corners and tilting functors in the Kac-Moody case

C Stroppel - arXiv preprint math/0605103, 2006 - arxiv.org
We study projective functors (ie direct summands of compositions of translations through
walls) for parabolic versions of $\cO $ as well as for integral regular blocks outside the …

Hereditary cotorsion pairs on extriangulated subcategories

Y Liu, P Zhou - arXiv preprint arXiv:2012.06997, 2020 - arxiv.org
Let $\mathcal B $ be an extriangulated category with enough projectives and enough
injectives. We define a proper $ m $-term subcategory $\mathcal G $ on $\mathcal B …

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

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 …

A Derived Gabriel–Popescu Theorem for t-Structures via Derived Injectives

F Genovese, J Ramos González - International Mathematics …, 2023 - academic.oup.com
We prove a derived version of the Gabriel–Popescu theorem in the framework of dg-
categories and t-structures. This exhibits any pretriangulated dg-category with a suitable t …

[PDF][PDF] On the relation between Auslander-Reiten (d+ 2)-angles and Serre duality

P Zhou - arXiv preprint arXiv:1910.01454, 2019 - researchgate.net
Let C be an (d+ 2)-angulated category with an d-suspension functor Σd. Our main results
show that every Serre functor on C is an (d+ 2)-angulated functor. We also show that C has a …

[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 …
