Feckly Reduced Rings [PDF]

Hacettepe Journal of Mathematics and Statistics, 2015
Let R be a ring with identity and J(R) denote the Jacobson radical of R. In this paper, we introduce a new class of rings called feckly reduced rings. The ring R is called feckly reduced if R=J(R) is a reduced ring. We investigate relations between feckly reduced rings and other classes of rings.

A note on connected reduced rings

Journal of Commutative Algebra, 2021
This 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 [PDF]

Canadian Mathematical Bulletin, 1980
We 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.

A bandwidth reducing token ring

Computer Networks and ISDN Systems, 1991
Abstract Bandwidth restrictions limit the use of twisted pair wires that are so convenient for building networks. A new design for token rings using twisted pair wires is presented. Bandwidth compression is achieved through the use of an adapter that generates a duobinary signal and is transparent to the users.
