Projective prime ideals and localisation in pi-rings [PDF]

open access: yes, 2001
The results here generalise [2, Proposition 4.3] and [9, Theorem 5.11]. We shall prove the following. THEOREM A. Let R be a Noetherian PI-ring. Let P be a non-idempotent prime ideal of R such that PR is projective. Then P is left localisable and RP is

Derivations in Prime Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1957
We prove two theorems that are easily conjectured, namely: (1) In a prime ring of characteristics not 2, if the iterate of two derivations is a derivation, then one of them is zero; (2) If d is a derivation of a prime ring such that, for all elements a of the ring, ad(a) -d(a)a is central, then either the ring is commutative or d is zero.

The Prime Spectra of Regular Rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2007
In this work, we study the prime spectrum of regular rings. Also we study some topological concepts as quasi-compact, compact, totally disconnected, and irreducible topological space in order to prove some new results on the prime spectrum of regular ...

About unital and non-unital duo rings [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
Several results about one-sided duo rings and duo rings are generalized from the case of unital rings to the case of arbitrary associative rings in this paper.

A one-sided Prime Ideal Principle for noncommutative rings

open access: yes, 2011
Completely prime right ideals are introduced as a one-sided generalization of the concept of a prime ideal in a commutative ring. Some of their basic properties are investigated, pointing out both similarities and differences between these right ideals ...

Prime essential rings [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 1991
A ring R is prime essential if R is semiprime and for each prime ideal P of R, P ∩ I ≠0 whenever I is a nonzero two-sided ideal of R. Examples of prime essential rings include rings of continuous functions and infinite products modulo infinite sums. We show that the class of prime essential rings is closed under many familiar operations; in particular,

A prime ideal principle for two-sided ideals

open access: yes, 2016
Many classical ring-theoretic results state that an ideal that is maximal with respect to satisfying a special property must be prime. We present a "Prime Ideal Principle" that gives a uniform method of proving such facts, generalizing the Prime Ideal ...

On rings with prime centers

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
Let R be a ring, and let C denote the center of R. R is said to have a prime center if whenever ab belongs to C then a belongs to C or b belongs to C. The structure of certain classes of these rings is studied, along with the relation of the notion of ...

Derivation Requirements on Prime Near-Rings for Commutative Rings

open access: yesJurnal Ilmu Dasar, 2019
Near-ring is an extension of ring without having to fulfill a commutative of the addition operations and left distributive of the addition and multiplication operations It has been found that some theorems related to a prime near-rings are commutative ...

Jordan left (?,?) -derivations Of ?-prime rings

open access: yesمجلة بغداد للعلوم, 2011
It was known that every left (?,?) -derivation is a Jordan left (?,?) – derivation on ?-prime rings but the converse need not be true. In this paper we give conditions to the converse to be true.
