The Real Spectrum of a Noncommutative Ring

open access: bronzeJournal of Algebra, 1997
Spaces of orderings were introduced by the second author in a series of w x papers 15]19 and various structure results were obtained generalizing results proved earlier for formally real fields by various people: E. Becker, w x L. Brocker, R.

S-J-Ideals: A Study in Commutative and Noncommutative Rings

open access: yesJournal of Mathematics
In this paper, we introduce the concept of S-J-ideals in both commutative and noncommutative rings. For a commutative ring R and a multiplicatively closed subset S, we show that many properties of J-ideals apply to S-J-ideals and examine their ...

On r-Noncommuting Graph of Finite Rings [PDF]

open access: yesAxioms, 2021
Let R be a finite ring and r∈R. The r-noncommuting graph of R, denoted by ΓRr, is a simple undirected graph whose vertex set is R and two vertices x and y are adjacent if and only if [x,y]≠r and [x,y]≠−r.

Noncommutative scheme theory and the Serre–Artin–Zhang–Verevkin theorem for semi-graded rings

open access: diamondJournal of Noncommutative Geometry, 2023
In this paper, we present a noncommutative scheme theory for the semi-graded rings generated in degree one defined by Lezama and Latorre [Internat. J. Algebra Comput.

Noncommutative Jordan Rings [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1971
Heretofore most investigations of noncommutative Jordan algebras have been restricted to algebras over fields of characteristic ≠ 2 \ne 2 in order to make use of the passage from a noncommutative Jordan algebra A \mathfrak {A} to the commutative Jordan algebra

On ring extensions for completely primary noncommutative rings [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1962
0. Introduction. It is the authors' purpose in this paper to initiate the study of ring extensions for completely N primary noncommutative rings which satisfy the ascending chain condition for right ideals (A.C.C.). We begin here by showing that every completely N primary ring R with A.C.C. is properly contained in just such a ring.

A Galois Theory for Noncommutative Rings [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1967
hntroduction. In 1944, Jacobson [4] developed a Galois theory for nonnormal and nonseparable fields; and, in 1949, Hochschild [3] used the techniques of Jacobson to present a Galois theory for division rings. These same techniques will be used in this paper to present a Galois theory for rings with identity element.

NONCOMMUTATIVE HILBERT RINGS [PDF]

open access: greenJournal of Algebra and Its Applications, 2004
Commutative rings in which every prime ideal is the intersection of maximal ideals are called Hilbert (or Jacobson) rings. This notion was extended to noncommutative rings in two different ways by the requirement that prime ideals are the intersection of maximal or of maximal left ideals, respectively.

Birational rowmotion on a rectangle over a noncommutative ring [PDF]

open access: yesCombinatorial Theory, 2022
We extend the periodicity of birational rowmotion for rectangular posets to the case when the base field is replaced by a noncommutative ring (under appropriate conditions). This resolves a conjecture from 2014.
