Reductions of triangulated categories and simple-minded collections

H Jin - arXiv preprint arXiv:1907.05114, 2019 - arxiv.org
Silting and Calabi-Yau reductions are important process in representation theory to
construct new triangulated categories from given one, which are similar to Verdier quotient …

Homological systems in triangulated categories

O Mendoza, V Santiago - Applied Categorical Structures, 2016 - Springer
We introduce the notion of homological systems Θ for triangulated categories. Homological
systems generalize, on one hand, the notion of stratifying systems in module categories, and …

Extensions of covariantly finite subcategories revisited

J He - Czechoslovak Mathematical Journal, 2019 - Springer
Extriangulated categories were introduced by Nakaoka and Palu by extracting the
similarities between exact categories and triangulated categories. A notion of homotopy …

Finitistic dimension conjectures via Gorenstein projective dimension

P Moradifar, J Šaroch - Journal of Algebra, 2022 - Elsevier
It is a well-known result of Auslander and Reiten that contravariant finiteness of the class P∞
fin (of finitely generated modules of finite projective dimension) over an Artin algebra is a …

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 …
