Enhanced Auslander-Reiten duality and tilting theory for singularity categories

N Hanihara, O Iyama - arXiv preprint arXiv:2209.14090, 2022 - arxiv.org
We establish a general method to construct triangle equivalences between the singularity
categories of (commutative and non-commutative) Gorenstein rings and the cluster …

Cluster categories of formal DG algebras and singularity categories

N Hanihara - Forum of Mathematics, Sigma, 2022 - cambridge.org
Given a negatively graded Calabi-Yau algebra, we regard it as a DG algebra with vanishing
differentials and study its cluster category. We show that this DG algebra is sign-twisted …

[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 …

Tilting and cluster tilting for quotient singularities

O Iyama, R Takahashi - Mathematische Annalen, 2013 - Springer
We shall show that the stable categories of graded Cohen–Macaulay modules over quotient
singularities have tilting objects. In particular, these categories are triangle equivalent to …

Auslander-Reiten duality for subcategories

R Hafezi - arXiv preprint arXiv:1705.06684, 2017 - arxiv.org
Auslander-Reiten duality for module categories is generalized to some sufficiently nice
subcategories. In particular, our consideration works for $\mathcal {P}^{<\infty}(\Lambda) …

Silting reduction in extriangulated categories

Y Liu, P Zhou, Y Zhou, B Zhu - arXiv preprint arXiv:2108.07964, 2021 - arxiv.org
Presilting and silting subcategories in extriangulated categories were introduced by Adachi
and Tsukamoto recently. In this paper, we prove that the Gabriel-Zisman localization …

A Beligiannis - Journal of Algebra, 2015 - Elsevier
We study homological properties of contravariantly finite rigid subcategories of an arbitrary
triangulated or abelian category, concentrating at the class of higher cluster tilting …

Eventually homological isomorphisms and Gorenstein projective modules

Y Qin, D Shen - Science China Mathematics, 2023 - Springer
We prove that a certain eventually homological isomorphism between module categories
induces triangle equivalences between their singularity categories, Gorenstein defect …
