Relative singularity categories and Gorenstein-projective modules

XW Chen - arXiv preprint arXiv:0709.1762, 2007 - arxiv.org
We introduce the notion of relative singularity category with respect to any self-orthogonal
subcategory $\omega $ of an abelian category. We introduce the Frobenius category of …

Relative singularity categories and Gorenstein‐projective modules

XW Chen - Mathematische Nachrichten, 2011 - Wiley Online Library
We introduce the notion of relative singularity category with respect to a self‐orthogonal
subcategory ω of an abelian category. We introduce the Frobenius category of ω‐Cohen …

Indecomposable pure-injective objects in stable categories of Gorenstein-projective modules over Gorenstein orders

T Nakamura - arXiv preprint arXiv:2209.15630, 2022 - arxiv.org
We give a result of Auslander-Ringel-Tachikawa type for Gorenstein-projective modules
over a complete Gorenstein order. In particular, we prove that a complete Gorenstein order …

Singularity categories and singular equivalences for resolving subcategories

H Matsui, R Takahashi - Mathematische Zeitschrift, 2017 - Springer
Let XX be a resolving subcategory of an abelian category. In this paper we investigate the
singularity category D_ sg (X)= D^ b (mod\, X)/K^ b (proj (mod\, X)) D sg (X ̲)= D b (mod X …

Frobenius categories, Gorenstein algebras and rational surface singularities

M Kalck, O Iyama, M Wemyss, D Yang - Compositio Mathematica, 2015 - cambridge.org
We give sufficient conditions for a Frobenius category to be equivalent to the category of
Gorenstein projective modules over an Iwanaga–Gorenstein ring. We then apply this result …

On graded stable derived categories of isolated Gorenstein quotient singularities

K Ueda - Journal of Algebra, 2012 - Elsevier
We show the existence of a full exceptional collection in the graded stable derived category
of a Gorenstein isolated quotient singularity using a result of Orlov (2009)[Orl09]. We also …

[HTML][HTML] Relative singularity categories, Gorenstein objects and silting theory

J Wei - Journal of Pure and Applied Algebra, 2018 - Elsevier
We study singularity categories through Gorenstein objects in triangulated categories and
silting theory. Let ω be a presilting subcategory of a triangulated category T. We introduce …

[图书][B] Contributions to the Stable Derived Categories of Gorenstein Rings

V Gélinas - 2018 - search.proquest.com
The stable derived category D sg (R) of a Gorenstein ring R is defined as the Verdier
quotient of the bounded derived category D b (mod R) by the thick subcategory of perfect …

[HTML][HTML] Change of rings and singularity categories

S Oppermann, C Psaroudakis, T Stai - Advances in Mathematics, 2019 - Elsevier
We investigate the behavior of singularity categories and stable categories of Gorenstein
projective modules along a morphism of rings. The natural context to approach the problem …

The stable module category of a general ring

D Bravo, J Gillespie, M Hovey - arXiv preprint arXiv:1405.5768, 2014 - arxiv.org
For any ring R we construct two triangulated categories, each admitting a functor from R-
modules that sends projective and injective modules to 0. When R is a quasi-Frobenius or …
