An extension of the reflexive property of rings

Arab Journal of Mathematical Sciences, 2019
Mason introduced the notion of reflexive property of rings as a generalization of reduced rings. For a ring endomorphism α, Krempa studied α-rigid rings as an extension of reduced rings. In this note, we introduce the notion of α-quasi reflexive rings as

Locally finite profinite rings

, 2013
We investigate the structure of locally finite profinite rings. We classify (Jacobson-) semisimple locally finite profinite rings as products of complete matrix rings of bounded cardinality over finite fields, and we prove that the Jacobson radical of ...

Commutative Rings whose Matrix Rings are Baer Rings [PDF]

Proceedings of the American Mathematical Society, 1969
A ring R with unit element is a Baer ring if every left annihilator in R has the form Re, where e is an idempotent element. K. G. Wolfson has proven [3, Corollary 15], that if R is a Priifer ring (a commutative integral domain in which every finitely generated ideal is invertible) then the ring of endomorphisms of a finitely generated free module over ...

Additivity of nonlinear higher anti-derivable mappings on generalized matrix algebras

Electronic Research Archive, 2023
In this article, we proved that each nonlinear higher anti-derivable mapping on generalized matrix algebras is automatically additive. As for its applications, we find a similar conclusion on triangular algebras, full matrix algebras, unital prime rings ...

Vibration of Rotating and Revolving Planet Rings with Discrete and Partially Distributed Stiffnesses

Applied Sciences, 2020
Vibration properties of high-speed rotating and revolving planet rings with discrete and partially distributed stiffnesses were studied. The governing equations were obtained by Hamilton’s principle based on a rotating frame on the ring.

A CHARACTERIZATION OF BAER-IDEALS [PDF]

Journal of Algebraic Systems, 2014
An ideal I of a ring R is called right Baer-ideal if there exists an idempotent e 2 R such that r(I) = eR. We know that R is quasi-Baer if every ideal of R is a right Baer-ideal, R is n-generalized right quasi-Baer if for each I E R the ideal In is right

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Semicommutative and Armendariz Matrix Rings

Axioms
In this paper, we construct some interesting high-order upper triangular matrix rings, which have semicommutative and Armendariz properties. Also, the relatively maximality of these rings as subrings of certain matrix rings is considered.

On adequacy of full matrices

Математичні Студії, 2023
This paper deals with the following question: whether a ring of matrices or classes of matrices over an adequate ring or elementary divisor ring inherits the property of adequacy?

Matrix d.g. near-rings [PDF]

Proceedings of the Edinburgh Mathematical Society, 1998
Matrix near-rings had been defined by Meldrum and Van der Walt in 1986 and although a fair amount of results on the structure of these near-rings have been obtained since then, a satisfactory structure theory has yet to be developed for matrix d.g. near-rings.
