Dominant local rings and subcategory classification

R Takahashi - International Mathematics Research Notices, 2023 - academic.oup.com
We introduce a new notion of commutative noetherian local rings, which we call dominant.
We explore fundamental properties of dominant local rings and compare them with other …

On localizing subcategories of derived categories

R Takahashi - Journal of mathematics of Kyoto University, 2009 - projecteuclid.org
Let $ A $ be a commutative noetherian ring. In this paper, we interpret localizing
subcategories of the derived category of $ A $ by using subsets of Spec $ A $ and …

Local rings with quasi-decomposable maximal ideal

S Nasseh, R Takahashi - Mathematical Proceedings of the …, 2020 - cambridge.org
Let (R, 𝔪) be a commutative noetherian local ring. In this paper, we prove that if 𝔪 is
decomposable, then for any finitely generated R-module M of infinite projective dimension 𝔪 …

Classification of dominant resolving subcategories by moderate functions

R Takahashi - Illinois Journal of Mathematics, 2021 - projecteuclid.org
Let R be a commutative Noetherian ring. Denote by mod R the category of finitely generated
R-modules. In this paper, we study dominant resolving subcategories of mod R. We …

Classifying subcategories of modules

M Hovey - Transactions of the American Mathematical Society, 2001 - ams.org
Let $ R $ be the quotient of a regular coherent commutative ring by a finitely generated
ideal. In this paper, we classify all abelian subcategories of finitely presented $ R $-modules …

A few examples of local rings, II

J Nishimura - 2016 - projecteuclid.org
This is the second part of our three-part study titled “A few examples of local rings.” In the first
part, we collected the basic tools and well-known important examples. But, since almost all …

Complete intersections and derived categories

DJ Benson, JPC Greenlees - arXiv preprint arXiv:0906.4025, 2009 - arxiv.org
We propose a definition of when a triangulated category should be considered a complete
intersection. We show (using work of Avramov and Gulliksen) that for the derived category of …

Pure derived and pure singularity categories

T Cao, W Ren - Journal of Algebra and Its Applications, 2020 - World Scientific
Firstly, we compare the bounded derived categories with respect to the pure-exact and the
usual exact structures, and describe bounded derived category by pure-projective modules …
