Fuzzy maximal, radical and primary ideals of a ring

Information Sciences, 1991
This paper constitutes a further step in the straightforward fuzzification of the classical algebraic structures. More concretely the concepts: fuzzy maximal ideal, fuzzy prime ideal, fuzzy radical of a fuzzy ideal and fuzzy primary ideal of a ring are introduced and a lot of interesting properties are proved.

A Novel Free-Radical Ring Contraction of a Cyclic Carbamate

The Journal of Organic Chemistry, 2002
During a study on iodocyclocarbamation reactions of 2-styryl-4-piperidones, a novel ring contraction was observed. Iodocyclocarbamation of 2-styryl-4-piperidone 3 gave the bicyclic carbamate 4. Reduction of 4 under free-radical conditions effected a stereoselective ring contraction to provide oxazolidinone 6.

A note on quasi-p radical of associative rings

Applied Mathematics-A Journal of Chinese Universities, 1997
Let \(P\) be an arbitrary homomorphically closed property of associative rings. The author defines a quasi-\(P\) ideal of an associative ring \(A\). He then constructs a quasi-\(P\) radical \(QP(A)\) using transfinite induction. He also gives another characterization of the quasi-\(P\) radical: \(QP(A)=\bigcap\{I_\alpha:I_\alpha\) is an ideal of \(A ...

On the Associated Lie Ring and the Adjoint Group of a Radical Ring

Canadian Mathematical Bulletin, 1984
AbstractWe investigate connections between the associated Lie ring and the adjoint group of a radical ring, studying their upper central chains. Part of a conjecture of S. A. Jennings is proved, and one of our results improves a theorem of his.
