On the subcategories of n-torsionfree modules and related modules

S Dey, R Takahashi - Collectanea Mathematica, 2023 - Springer
Let R be a commutative noetherian ring. Denote by mod\, R mod R the category of finitely
generated R-modules. In this paper, we study n-torsionfree modules in the sense of …

Some characterizations of local rings via reducing dimensions

O Celikbas, S Dey, T Kobayashi, H Matsui - arXiv preprint arXiv …, 2022 - arxiv.org
In this paper we study homological dimensions of finitely generated modules over
commutative Noetherian local rings, called reducing homological dimensions. We obtain …

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 …

A study of the cohomological rigidity property

M Asgharzadeh, O Celikbas, A Sadeghi - arXiv preprint arXiv:2009.06481, 2020 - arxiv.org
In this paper, motivated by a work of Luk and Yau, and Huneke and Wiegand, we study
various aspects of the cohomological rigidity property of tensor product of modules over …

A generalization of the dimension and radius of a subcategory of modules and its applications

Y Mifune - arXiv preprint arXiv:2401.11153, 2024 - arxiv.org
Let $ R $ be a commutative noetherian local ring and denote by $\operatorname {mod} R $
the category of finitely generated $ R $-modules. In this paper, we give some evaluations of …

Some Categorical Aspects of Commutative Algebra

S Dey - 2023 - search.proquest.com
The purpose of this work is to study commutative Noetherian rings by studying certain
subcategories of the category of finitely generated modules over such rings. We begin by …

Resolving subcategories whose finitely presented module categories are abelian

R Takahashi - Comptes Rendus. Mathématique, 2021 - numdam.org
Let X be an additive full subcategory of an abelian category. It is a classical fact that if X is
contravariantly finite, then the category modX of finitely presented right X-modules is …

Y MIFUNE - s-murai.w.waseda.jp
Let R be a commutative noetherian local ring. Denote by mod R the category of finitely
generated R-modules. The concept of the radius of a full subcategory of mod R has been …
