On pure subrings of sp-groups

A Amini, B Amini, E Momtahan - Communications in Algebra, 2024 - Taylor & Francis
Let G be a sp-group such that for every prime p, Gp is elementary. We show that End Z (G) is
a sp-group and every subring R of∏ End Z (G p), containing⊕ End Z (G p) is pure if and …

Some properties of algebras of real-valued measurable functions

H Azadi, M Henriksen, E Momtahan - Acta Mathematica Hungarica, 2009 - akjournals.com
Measures and measurable functions are used primarily as tools for carrying out various
calculations to increase our knowledge. We learn how to combine them in various ways by …

On limit models and parametrized noetherian rings

M Mazari-Armida - arXiv preprint arXiv:2405.20214, 2024 - arxiv.org
We study limit models in the abstract elementary class of modules with embeddings as
algebraic objects. We characterize parametrized noetherian rings using the degree of …

On Infinite direct products of Rings modulo their direct sums

E Momtahan - Journal of the Iranian Mathematical Society, 2024 - jims.ims.ir
In this article, inspiring with a result due to OAS Karamzadeh, we examine the $\prod_ {i\in I}
R_i/\oplus_ {i\in I} R_i $, where $\{R_i\} _ {i\in I} $ is an infinite family of rings. We observe …

-Injective group rings

L Shen - Journal of Algebra and Its Applications, 2020 - World Scientific
Recall that a ring R is called right ℵ 0-injective if every homomorphism from a countably
generated right ideal of R to RR can be extended to a homomorphism from RR to RR. These …

[PDF][PDF] Remarks On -Injectivity

E Momtahan - arXiv preprint arXiv:0910.1995, 2009 - arxiv.org
In this article, by R we mean an associative ring with identity and M is a unitary R-module.
An R-module M is said to be R0-injective (f-injective) if every (module) homorphism f∈ …

[PDF][PDF] Projective maximal submodules of extending regular modules

E Momtahan - Bulletin of the Iranian Mathematical Society, 2012 - bims.iranjournals.ir
We show that a projective maximal submodule of afinitely generated, regular, extending
module is a directsummand. Hence, every finitely generated, regular, extendingmodule with …
