On commutativity of σ-prime rings [PDF]

open access: yes, 2006
Let R be a 2-torsion free σ-prime ring having a σ-square closed Lie ideal U and an automorphism T centralizing on U. We prove that if there exists u0 in Saσ(R) with Ru0 ⊂ U and if T commutes with σ on U, then U is contained in the center of R.

SOME EXAMPLES OF ARMENDARIZ RINGS [PDF]

open access: yes, 2017
We construct various examples of Armendariz and related rings by reviewing and extending some results concerning the structure of monoid M. In particular, we give some examples of Armendariz rings related to a monoid.

Abelian Modules [PDF]

open access: yes, 2009
In this note, we introduce abelian modules as a generalization of abelian rings. Let R be an arbitrary ring with identity. A module M is called abelian if, for any m 2 M and any a 2 R, any idempotent e 2 R, mae = mea.

Commutativity of associative rings through a Streb's classification [PDF]

open access: yes, 1997
summary:Let $m \geq 0, ~r \geq 0, ~s \geq 0, ~q \geq 0$ be fixed integers. Suppose that $R$ is an associative ring with unity $1$ in which for each $x,y \in R$ there exist polynomials $f(X) \in X^{2} \mbox{$Z \hspace{-2.2mm} Z$}[X], ~g(X), ~h(X) \in X ...

First Order Calculi with Values in Right--Universal Bimodules

open access: yes, 1996
The purpose of this note is to show how calculi on unital associative algebra with universal right bimodule generalize previously studied constructions by Pusz and Woronowicz [1989] and by Wess and Zumino [1990] and that in this language results are in a

Derivations and commutativity of σ-prime rings, [PDF]

open access: yes, 2006
Let R be a σ-prime ring with characteristic not two and d be a nonzero derivation of R commuting with σ. The purpose of this paper is to give suitable conditions under which R must be commutative.

Endo-principally Projective Modules [PDF]

open access: yes, 2013
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 projective (or simply p.p.) rings and Baer modules.

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.
