Stable range conditions for abelian and duo rings

open access: yesМатематичні Студії, 2022
The article deals with the following question: when does the classical ring of quotients of a duo ring exist and idempotents in the classical ring of quotients $Q_{Cl} (R)$ are there idempotents in $R$?

On Von Neumann Regular Rings [PDF]

open access: yesCanadian Mathematical Bulletin, 1974
Recently, in the Research Problems of Canadian Mathematical Bulletin, Vol. 14, No. 4, 1971, there appeared a problem which asks “Is a prime Von Neumann regular ring pimitive?” While we are not able to settle this question one way or the other, we prove that in a Von Neumann regular ring, there is a maximal annihilator right ideal if and only if there ...

Chromatic Number and some Properties of Pseudo-Von Neumann Regular graph of Cartesian Product of Rings

open access: yesTikrit Journal of Pure Science, 2020
Let R be a commutative ring, the Pseudo – Von Neumann  regular graph of the ring R is define as a graph whose vertex set consists of all elements of R and any two distinct vertices a and b are adjacent if and only if , this graph is denoted by P-VG(R ...

A-D3 Modules and A-D4 Modules

open access: yesJournal of Mathematics, 2023
Let A be a class of some right R-modules that is closed under isomorphisms, and let M be a right R-module. Then M is called A-D3 if, whenever N and K are direct summands of M with M=N+K and M/K∈A, then N∩K is also a direct summand of M; M is called an A ...

Classification of Boolean algebras through von Neumann regular $\mathcal{C}^{\infty}-$rings [PDF]

open access: yesCategories and General Algebraic Structures with Applications
In this paper, we introduce the concept of a ``von Neumann regular $\mathcal{C}^{\infty}$-ring", which is a model for a specific equational theory.

Trivial Ring Extension of Suitable-Like Conditions and some properties [PDF]

open access: yesمجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2018
We investigate the transfer of the notion of suitable rings along with related concepts, such as potent and semipotent rings, in the general context of the trivial ring extension, then we put these results in use to enrich the literature with new ...

Injective and coherent endomorphism rings relative to some matrices

open access: yesOpen Mathematics, 2023
Let MM be a right RR-module with S=End(MR)S={\rm{End}}\left({M}_{R}). Given two cardinal numbers α\alpha and β\beta and a row-finite matrix A∈RFMβ×α(S)A\in {{\rm{RFM}}}_{\beta \times \alpha }\left(S), SM{}_{S}M is called injective relative to AA if ...

On n-flat modules and n-Von Neumann regular rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
We show that each R-module is n-flat (resp., weakly n-flat) if and only if R is an (n,n−1)-ring (resp., a weakly (n,n−1)-ring). We also give a new characterization of n-Von Neumann regular rings and a characterization of weak n-Von Neumann regular rings ...

K1 of Von Neumann regular rings

open access: yesJournal of Pure and Applied Algebra, 1984
For certain rings and \(C^*\)-algebras R, the group \(K_ 1(R)\) is shown to equal the abelianization of the unit group U(R). For instance, this is proved for every \(C^*\)-algebra with unitary 1-stable range, for every \(AW^*\)-algebra, and for every unit-regular ring in which 2 is invertible.
