Group-regular rings [PDF]

open access: yes, 2019
We propose different generalizations of unit-regularity of elements in general rings (non necessarily unital rings). We then study general rings for which all elements have these properties.

On Noncommutative Generalisations of Boolean Algebras [PDF]

open access: yes, 2019
Skew Boolean algebras (SBA) and Boolean-like algebras (nBA) are one-pointed and n-pointed noncommutative generalisation of Boolean algebras, respectively.

Polynomial extensions of cP-Baer rings

open access: yes, 2023
Birkenmeier and Heider, in [2], say that a ring R is right cP-Baer if the right annihilator of a cyclic projective right R-module in R is generated by an idempotent. These rings are a generalization of the right p.q.-Baer and abelian rings.

Topology and monoid representations

open access: yes, 2023
The goal of this paper is to use topological methods to compute $\mathrm{Ext}$ between an irreducible representation of a finite monoid inflated from its group completion and one inflated from its group of units, or more generally coinduced from a ...

ON ANNIHILATOR PROPERTIES OF INVERSE SKEW POWER SERIES RINGS [PDF]

open access: yes, 2015
Let $alpha$ be an automorphism of a ring $R$. The authors [On skewinverse Laurent-serieswise Armendariz rings, Comm. Algebra 40(1)(2012) 138-156] applied the concept of Armendariz rings to inverseskew Laurent series rings and introduced skew ...

Semicentral idempotents in the multiplication ring of a centrally closed prime ring [PDF]

open access: yes, 2012
Let R be a ring and let M(R) stand for the multiplication ring of R. An idempotent E in M(R) is called left semicentral if its range E(R) is a right ideal of R.

Semiassociative algebras over a field

open access: yes, 2023
An associative central simple algebra is a form of matrices, because a maximal \'{e}tale subalgebra acts on the algebra faithfully by left and right multiplication.

On Principally Quasi-Baer Modules [PDF]

open access: yes, 2011
Let R be an arbitrary ring with identity and M a right R-module with S = EndR(M). In this paper, we introduce a class of modules that is a generalization of principally quasi-Baer rings and Baer modules.

GENERALIZED BAER RINGS [PDF]

open access: yes, 2020
We investigate the question whether the p.q.-Baer center of a ring R can be extended to R. We give several counterexamples to this question and consider some conditions under which the answer may be affirmative.

Isomorphisms of Formal Matrix Rings with Zero Trace Ideals [PDF]

open access: yes, 2018
© 2018, Pleiades Publishing, Ltd. We obtain explicit criteria for the isomorphism of formal matrix rings with zero trace ideals. In particular, we consider the case of formal upper-triangular matrix rings with semicentral reduced rings on the principal ...
