LEFT APP-RINGS OF SKEW GENERALIZED POWER SERIES [PDF]

open access: yesJournal of Algebra and Its Applications, 2011
A ring R is called a left APP-ring if the left annihilator lR(Ra) is right s-unital as an ideal of R for any a ∈ R. Let R be a ring, (S, ≤) be a commutative strictly ordered monoid and ω: S → End (R) be a monoid homomorphism. The skew generalized power series ring [[RS, ≤, ω]] is a common generalization of (skew) polynomial rings, (skew) power series ...

On t-closedness of generalized power series rings

open access: yesJournal of Pure and Applied Algebra, 2002
Let \(A\subset B\) be an extension of commutative rings. We say that \(A\) is \(t\)-closed in \(B\) if, whenever \(b^2-ab\), \(b^3-ab^2\in A\) for \(a\in A\) and \(b\in B\), then \(b\in A\). We say that property \({\mathcal P}_1(A,B)\) holds if, whenever \(ab\in A\) for \(a\in A\) and \(b\in B\), then \(ab^2\in A\).

ALMOST right (left) SEMICLEAN RINGS of SKEW GENERALIZED POWER SERIES

open access: yesJournal of Scientific Research in Science
We extend the notions of almost clean, n-almost clean, and almost semiclean to the non-commutative setting. Then, we demonstrate that under specific conditions that the skew generalized power series rings S[[T,w]] is almost right (left) semiclean if ...

PS-Modules over Ore Extensions and Skew Generalized Power Series Rings [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2015
A right R-module MR is called a PS-module if its socle, SocMR, is projective. We investigate PS-modules over Ore extension and skew generalized power series extension.

A STUDY OF DERIVATIONS AND LINEAR MAPPINGS ON SKEW GENERALIZED POWER SERIES MODULES

open access: yesBarekeng
This paper investigates the structure of skew generalized power series modules over skew generalized power series rings, emphasizing the extension of derivations in this context. We define and study additive mappings that generalize classical derivations

REVERSIBLE SKEW GENERALIZED POWER SERIES RINGS [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2011
AbstractIn this note we show that there exist a semiprime ring R, a strictly ordered artinian, narrow, unique product monoid (S,≤) and a monoid homomorphism ω:S⟶End(R) such that the skew generalized power series ring R[[S,ω]] is semicommutative but R[[S,ω]] is not reversible. This answers a question posed in Marks et al. [‘A unified approach to various

Rings of Generalized Power Series

open access: yesJournal of Algebra, 1994
[For part I see Abh. Math. Semin. Univ. Hamb. 61, 15-33 (1991; Zbl 0751.13005).] Consider a strictly ordered monoid \(S\) and a commutative ring \(R\) with unit element. A generalized power series with coefficients in \(R\) and exponents in \(S\) is a mapping \(f:S \to R\) having artinian and narrow support \((\text{supp} (f))\), that is every strictly

On n-root closedness of generalized power series rings over pairs of rings

open access: yesJournal of Pure and Applied Algebra, 1999
This paper deals with \(n\)-root closedness of generalized power series rings (as defined by P. Ribenboim), thus generalizing previous results on classical power series rings by \textit{D. F. Anderson, D. E. Dobbs} and \textit{M. Roitman} [J. Pure Appl. Algebra 114, No. 2, 111-131 (1997; Zbl 0926.13012)].

Existence of prime elements in rings of generalized power series [PDF]

open access: yesJournal of Symbolic Logic, 2001
AbstractThe fieldK((G)) of generalized power series with coefficients in the fieldKof characteristic 0 and exponents in the ordered additive abelian groupGplays an important role in the study of real closed fields. Conway and Gonshor (see [2, 4]) considered the problem of existence of non-standard irreducible (respectively prime) elements in the huge ...

Noetherian rings of generalized power series

open access: yesJournal of Pure and Applied Algebra, 1992
Rings of generalized power series include, as particular cases, monoid rings, ordinary formal power series rings, rings of arithmetical functions, etc. The paper investigates when a ring of generalized power series is noetherian. As a consequence, many interesting classes of examples of noetherian rings are obtained.
