A Note on Semiprime Rings with Torsionless Injective Envelope

open access: yes, 1973
Satyanarayana establishes in [6] that a semiprime right selfinjective ring with ACC on annihilator right ideals is semisimple Artinian, thereby extending a similar result of Koh [5] for prime rings.

Lie Ideals and Homoderivations in Semiprime Rings

open access: yesMathematics
Let S be a 2-torsion free semiprime ring and U be a noncentral square-closed Lie ideal of S. An additive mapping ℏ on S is defined as a homoderivation if ℏ(ab)=ℏ(a)ℏ(b)+ℏ(a)b+aℏ(a) for all a,b∈S. In the present paper, we shall prove that ℏ is a commuting

Identities with derivations and automorphisms on semiprime rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
The purpose of this paper is to investigate identities with derivations and automorphisms on semiprime rings. A classical result of Posner states that the existence of a nonzero centralizing derivation on a prime ring forces the ring to be commutative ...

IDENTITIES WITH MULTIPLICATIVE GENERALIZED (α,α)-DERIVATIONS OF SEMIPRIME RINGS

open access: yes
Let R be a semiprime ring and α be an automorphism of R. A mapping F : R → R (not necessarily additive) is called multiplicative generalized (α,α)derivation if there exists a unique (α,α)-derivation d of R such that F(xy) = F(x)α(y) + α(x)d(y) for all x ...

Symmetric Reverse n-Derivations on Ideals of Semiprime Rings

open access: yesAxioms
This paper focuses on examining a new type of n-additive map called the symmetric reverse n-derivation. As implied by its name, it combines the ideas of n-additive maps and reverse derivations, with a 1-reverse derivation being the ordinary reverse ...

Normalizing extensions of semiprime rings

open access: yes, 2004
In this paper we study normalizing extensions of semiprime rings. For an extension S of R we construct the canonical torsion-free S ∗ , which is a normalizing extension of the symmetric ring of quotients Q of R.

Center-like Subsets in Semiprime Rings with Multiplicative Derivations

open access: yesAxioms
We introduce center-like subsets Z∘*(A,d),Z∘**(A,d), where A is the ring and d is the multiplicative derivation. In the following, we take a new derivation for the center-like subsets existing in the literature and establish the relations between these ...

On nilpotent derivations of semiprime rings

open access: yes, 1992
In this paper we study nilpotent derivations of semiprime rings. An associative derivation d: R → R is an additive mapping on a ring R satisfying d(xy) = d(x) y + xd(y) for all x, y ϵ R.
