[HTML][HTML] Auslander–Gorenstein algebras and precluster tilting
O Iyama, Ø Solberg - Advances in Mathematics, 2018 - Elsevier
We generalize the notions of n-cluster tilting subcategories and τ-selfinjective algebras into
n-precluster tilting subcategories and τ n-selfinjective algebras, where we show that a …

An introduction to higher Auslander–Reiten theory
This article consists of an introduction to Iyama's higher Auslander–Reiten theory for Artin
algebras from the viewpoint of higher homological algebra. We provide alternative proofs of …

[HTML][HTML] Axiomatizing subcategories of abelian categories
S Kvamme - Journal of Pure and Applied Algebra, 2022 - Elsevier
We investigate how to characterize subcategories of abelian categories in terms of intrinsic
axioms. In particular, we find axioms which characterize generating cogenerating functorially …

New interpretations of the higher Stasheff–Tamari orders
NJ Williams - Advances in Mathematics, 2022 - Elsevier
Abstract In 1996, Edelman and Reiner defined the two higher Stasheff–Tamari orders on
triangulations of cyclic polytopes and conjectured them to coincide. We open up an …

The index in -exact categories
Starting from its original definition in module categories with respect to projective modules,
the index has played an important role in various aspects of homological algebra …

Cluster subalgebras and cotorsion pairs in Frobenius extriangulated categories
W Chang, P Zhou, B Zhu - Algebras and Representation Theory, 2019 - Springer
Nakaoka and Palu introduced the notion of extriangulated categories by extracting the
similarities between exact categories and triangulated categories. In this paper, we study …

[HTML][HTML] -Cluster tilting subcategories of singularity categories
S Kvamme - Mathematische Zeitschrift, 2021 - Springer
For an exact category EE with enough projectives and with ad Z d Z-cluster tilting
subcategory, we show that the singularity category of EE admits ad Z d Z-cluster tilting …

The role of gentle algebras in higher homological algebra
J Haugland, KM Jacobsen, S Schroll - Forum Mathematicum, 2022 - degruyter.com
We investigate the role of gentle algebras in higher homological algebra. In the first part of
the paper, we show that if the module category of a gentle algebra Λ contains ad-cluster …
