-tilting theory

T Adachi, O Iyama, I Reiten - Compositio Mathematica, 2014 - cambridge.org
The aim of this paper is to introduce τ-tilting theory, which 'completes'(classical) tilting theory
from the viewpoint of mutation. It is well known in tilting theory that an almost complete tilting …

Cluster-tilted algebras are Gorenstein and stably Calabi–Yau

B Keller, I Reiten - Advances in Mathematics, 2007 - Elsevier
We prove that in a 2-Calabi–Yau triangulated category, each cluster tilting subcategory is
Gorenstein with all its finitely generated projectives of injective dimension at most one. We …

Cluster structures for 2-Calabi–Yau categories and unipotent groups

AB Buan, O Iyama, I Reiten, J Scott - Compositio Mathematica, 2009 - cambridge.org
We investigate cluster-tilting objects (and subcategories) in triangulated 2-Calabi–Yau and
related categories. In particular, we construct a new class of such categories related to …

Auslander correspondence

O Iyama - Advances in Mathematics, 2007 - Elsevier
We study Auslander correspondence from the viewpoint of higher-dimensional analogue of
Auslander–Reiten theory [O. Iyama, Higher dimensional Auslander–Reiten theory on …

n-exangulated categories (I): Definitions and fundamental properties

M Herschend, Y Liu, H Nakaoka - Journal of Algebra, 2021 - Elsevier
For each positive integer n we introduce the notion of n-exangulated categories as higher
dimensional analogues of extriangulated categories defined by Nakaoka–Palu. We …

Cluster tilting for higher Auslander algebras

O Iyama - Advances in Mathematics, 2011 - Elsevier
The concept of cluster tilting gives a higher analogue of classical Auslander correspondence
between representation-finite algebras and Auslander algebras. The n-Auslander–Reiten …

From triangulated categories to abelian categories: cluster tilting in a general framework

S Koenig, B Zhu - Mathematische Zeitschrift, 2008 - Springer
A general framework for cluster tilting is set up by showing that any quotient of a triangulated
category modulo a tilting subcategory (ie, a maximal 1-orthogonal subcategory) carries an …

Fomin-Zelevinsky mutation and tilting modules over Calabi-Yau algebras

O Iyama, I Reiten - American Journal of Mathematics, 2008 - muse.jhu.edu
We say that an algebra $\Lambda $ over a commutative noetherian ring $ R $ is Calabi-Yau
of dimension $ d $($ d $-CY) if the shift functor $[d] $ gives a Serre functor on the bounded …
