On reduced rank of triangular matrix rings
Journal of Algebra and Its Applications, 2015We determine conditions under which a generalized triangular matrix ring has finite reduced rank, in the general torsion-theoretic sense. These are applied to characterize certain orders in Artinian rings, and to show that if each homomorphic image of a ring S has finite reduced rank, then so does the ring of lower triangular matrices over S.

Let R be a ring with identity and J(R) denote the Jacobson radical ofR. In this paper, we introduce a new class of rings called feckly reducedrings. The ring R is called feckly reduced if R/J(R) is a reduced ring.We investigate relations between feckly reduced rings and other classesof rings.

A Reduced Output Ringing CMOS Buffer
IEEE Transactions on Circuits and Systems II: Express Briefs, 2007In a multichip module, the parasitic elements of the interconnections influence the performance of the devices enclosed in the package. Phenomena such as ground bounce, cross-talk, propagation delay, and over/undershoot will degrade the data signal integrity. This brief describes an output buffer structure, consisting of a double feedback loop.

Actions of Lie Superalgebras on Reduced Rings
Algebras and Representation Theory, 2007The authors consider actions of finite-dimensional Hopf algebras on reduced and graded-reduced algebras and study the question of when the subalgebra of invariants is non-zero. The first result says that if \(R\) is a graded-reduced ring of characteristic \(p>2\) acted on by a finitely generated restricted \(K\)-Lie superalgebra \(L\), where \(K\) is a

Abstract In this paper we introduce a partial order relation in a reduced near-ring and show that the set of all idempotents of a reduced near-ring with identity forms a Boolean algebra under this partial ordering. Further we introduce the notions hyper atom and orthogonal subsets in a reduced near-ring with identity and show that a reduced near-ring

A note on connected reduced rings
Journal of Commutative Algebra, 2021This short note illustrates a constructive proof of a characterisation of reduced and connected rings, whereas the cassical proof makes an apparently fundamental use of prime ideals and Krull's Lemma. Avoiding these constructively non-admissible tools has been achieved by using instead radical ideals and their properties, which are constructively ...

A Simple Proof of a Theorem on Reduced Rings
Canadian Mathematical Bulletin, 1980We give a simple proof of a theorem by Andrunakievič and Rjabuhin which states that a reduced ring is a subdirect product of entire rings. Our proof makes no use of m-systems and is in some sense similar to the proof of the corresponding theorem in the commutative case due to Krull.A reduced ring is a ring without non-zero nilpotent elements.

NPP RINGS, REDUCED RINGS AND SNF RINGS
2008A ring R is called left NP P if for any nilpotent element a of R, l(a) = Re, e2 = e ∈ R. A right R−module M is called N f lat if for each a ∈ N(R), the Z−module map 1M ⊗ i : M ⊗R Ra −→ M ⊗R R is monic, where i : Ra ,→ R is the inclusion map. A ring R is called right SNF if every simple right R−module is N f lat. In this paper, we first show that a ring

Rings decomposed into direct sums of nil rings and certain reduced rings
Mathematical Journal of Okayama University, 1985Let R be a ring, E the set of idempotents of R, and N the set of nilpotents. For \(x\in R\), denote by r(x) the right annihilator of x; call x a right p.p. element if there exists \(e\in E\) such that \(xe=x\) and \(r(x)=r(e)\). Let P be the set of all right p.p. elements, and call R a generalized right p.p.

Modules with reduced endomorphism rings
Journal of Algebra and Its ApplicationsIn this paper, we study endo-reduced modules as modules whose endomorphism rings have no nonzero nilpotent elements. We characterize their properties for different classes of modules, including [Formula: see text]-non-singular modules, multiplication modules and finitely generated modules over commutative Dedekind domains.
