Feebly Baer Rings and Modules

Communications in Algebra, 2014
A right module M over a ring R is called feebly Baer if, whenever xa = 0 with x ∈ M and a ∈ R, there exists e2 = e ∈ R such that xe = 0 and ea = a. The ring R is called feebly Baer if RR is a feebly Baer module. These notions are motivated by the commutative analog discussed in a recent paper by Knox, Levy, McGovern, and Shapiro [6].

Baer and Baer *-ring characterizations of Leavitt path algebras [PDF]

Journal of Pure and Applied Algebra, 2018
We characterize Leavitt path algebras which are Rickart, Baer, and Baer $*$-rings in terms of the properties of the underlying graph. In order to treat non-unital Leavitt path algebras as well, we generalize these annihilator-related properties to locally unital rings and provide a more general characterizations of Leavitt path algebras which are ...

Conrad’s Partial Order on P.Q.-Baer *-Rings

Discussiones Mathematicae - General Algebra and Applications, 2018
We prove that a p.q.-Baer *-ring forms a pseudo lattice with Conrad’s partial order and also characterize p.q.-Baer *-rings which are lattices. The initial segments of a p.q.-Baer *-ring with the Conrad’s partial order are shown to be an orthomodular ...

Polynomial extensions of Baer and quasi-Baer rings

Journal of Pure and Applied Algebra, 2001
A ring \(R\) is called (quasi-)Baer ring if the right annihilator of every (ideal) non-empty subset of \(R\) is generated, as a right ideal, by an idempotent of \(R\). Theorem 1.2. Let \(R\) be a quasi-Baer ring. Then the following extension rings are quasi-Baer rings, where \(X\) is an arbitrary nonempty set of not necessarily commuting indeterminates

Anillos separables, de baer y pp-anillos

Revista de Matemática: Teoría y Aplicaciones, 2009
Keimel introduced the notion of proyectability in the class of lattice-ordered rings and f-rings in [5]. Here we introduce a similar notion forgeting the lattice and ordered structure of the ring and interpretating the orthogonality within the ...

A Unified Approach to Generalizing π-Extending and π-Baer Rings

Journal of Mathematics
This paper introduces and examines the right essentially π-Baer ring property, which serves as a new extension of the π-extending and π-Baer ring conditions. The initial phase of the study involves the development of several foundational results.

On twisted ordered monoid rings over quasi-Baer rings

Le Matematiche, 2011
In this paper we show that if M is an Ordered monoid then the twisted monoid ring R^T M is (left principally) quasi-Baer if and only if R is (left principally) quasi-Baer.

Skew Hurwitz series over quasi Baer and PS-rings

Le Matematiche, 2012
In this paper, we consider some properties of rings which are shared by the ring R and the ring T = (HR, σ ) of skew Hurwitz series. In particular we show that:1) If R is a ring with char(R) = 0 and σ is an R -automorphism such that σ (e) = e and the ...

Energy Landscapes in Chemical Reactions and Transport. [PDF]

Chemphyschem
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Semi-Baer and Semi-Quasi Baer Properties of Skew Generalized Power Series Rings [PDF]

Assiut University Journal of Multidisciplinary Scientific Research
Let R be a ring with identity, (S,≤) an ordered monoid, ω:S→End(R) a monoid homomorphism, and A=R[[S,ω]] the ring of skew generalized power series. The concepts of semi-Baer and semi-quasi Baer rings were introduced by Waphare and Khairnar as extensions ...
