Generalized trace submodules and centers of endomorphism rings

J Lyle - arXiv preprint arXiv:2311.00220, 2023 - arxiv.org
Let $ R $ be a commutative Noetherian local ring and $ M $ a finitely generated $ R $-
module. We introduce a general form of the classically studied trace map that unifies several …

Some homological properties of modules over a complete intersection, with applications

H Dao - Commutative Algebra: Expository Papers Dedicated to …, 2013 - Springer
We survey some recent developments in understanding homological properties of finitely
generated modules over a complete intersection. These properties mainly concern with …

Local cohomology and Foxby classes

M Ahmadi, A Rahimi - Acta Mathematica Hungarica, 2024 - Springer
Let R be a commutative Noetherian ring and I a proper ideal of R. In this paper, we study
finitely generated R-modules M with only one non-vanishing local cohomology module\({H} …

The Krull Dimension of Certain Semiprime Modules Versus Their -Shortness

SM Javdannezhad, N Shirali - Mediterranean Journal of Mathematics, 2018 - Springer
We study the R-modules M which are finitely generated, quasi-projective and self-generator
(briefly called FQS FQS modules). We extend some basic results from semiprime rings to …

The dimension of a subcategory of modules

H Dao, R Takahashi - Forum of Mathematics, Sigma, 2015 - cambridge.org
Let R be a commutative noetherian local ring. As an analog of the notion of the dimension of
a triangulated category defined by Rouquier, the notion of the dimension of a subcategory of …

co-Hopfian Modules

FC Leary - arXiv preprint arXiv:2201.09961, 2022 - arxiv.org
If $ R $ is a ring with 1, we call a unital left $ R $-module $ M $ co-Hopfian (Hopfian) in the
category of left $ R $-modules if any monic (epic) endomorphism of $ M $ is an …

Criteria for flatness and injectivity

N Epstein, Y Yao - Mathematische Zeitschrift, 2012 - Springer
Let R be a commutative Noetherian ring. We give criteria for flatness of R-modules in terms
of associated primes and torsion-freeness of certain tensor products. This allows us to …

A note on self-small modules over RM-domains

U Albrecht, S Breaz - Journal of Algebra and Its Applications, 2014 - World Scientific
This paper provides two new characterizations of RM-domains, ie domains satisfying the
restricted minimum condition. A Noetherian domain is a RM-domain if and only if every …
