[HTML][HTML] Higher Auslander–Solberg correspondence for exact categories

JF Grevstad - Journal of Pure and Applied Algebra, 2024 - Elsevier
We introduce the concept of an n-minimal Auslander–Gorenstein category and n-precluster
tilting subcategory. With this, we create an analog of the higher Auslander–Solberg …

Rigid objects, triangulated subfactors and abelian localizations

A Beligiannis - Mathematische Zeitschrift, 2013 - Springer
We show that the abelian category mod-X of coherent functors over a contravariantly finite
rigid subcategory X in a triangulated category T is equivalent to the Gabriel–Zisman …

Cut notions in extriangulated categories related to Auslander-Buchweitz theory and cotorsion theory

M Huerta, O Mendoza, C Sáenz, V Santiago - arXiv preprint arXiv …, 2022 - arxiv.org
In this work we introduce notions in Auslander-Buchweitz theory and cotorsion theory in
extriangulated categories which extend the given ones for abelian categories. Although …

Schur's lemma for exact categories implies abelian

H Enomoto - Journal of Algebra, 2021 - Elsevier
We show that for a given exact category, there exists a bijection between semibricks
(pairwise Hom-orthogonal set of bricks) and length wide subcategories (exact extension …

Realisation functors in tilting theory

C Psaroudakis, J Vitória - Mathematische Zeitschrift, 2018 - Springer
Derived equivalences and t-structures are closely related. We use realisation functors
associated to t-structures in triangulated categories to establish a derived Morita theory for …

Notes on triangulated categories

T Fritz - arXiv preprint arXiv:1407.3765, 2014 - arxiv.org
We give an elementary introduction to the theory of triangulated categories covering their
axioms, homological algebra in triangulated categories, triangulated subcategories, and …

Quotients of exact categories by pseudo-cluster-tilting subcategories

J Xu, Y Zheng - Communications in Algebra, 2023 - Taylor & Francis
We introduce the concept of a pseudo-cluster-tilting subcategory from the viewpoint of the
fact that the quotient of an exact category by a cluster-tilting subcategory is an abelian …

Parametrized higher category theory and higher algebra: Expos\'e I--Elements of parametrized higher category theory

C Barwick, E Dotto, S Glasman, D Nardin… - arXiv preprint arXiv …, 2016 - arxiv.org
We introduce the basic elements of the theory of parametrized $\infty $-categories and
functors between them. These notions are defined as suitable fibrations of $\infty …
