Not-so-fuzzy fuzzy ideals

Fuzzy Sets and Systems, 1990
The authors look for algebraic structures which do not admit proper fuzzy substructures. The main answer is the following: Theorem. If a ring R is Boolean, Artinian or a principal ideal domain, then in R any proper prime fuzzy ideal P has supp P\(=\{0\}\). As a generalization they get a characterization of rings with finite chains of ideals.

Fuzzy ideals and semiprime fuzzy ideals in semigroups

Information Sciences, 2009
The results of this paper concern \(\varphi\)-fuzzy ideals in a \(\varphi\)-fuzzy semigroup, where \(\varphi\) is either a pseudo-\(t\)-norm or a weak pseudo-\(t\)-norm. Let \((L,\leq)\) be a lattice with top element 1 and bottom element 0. A pseudo-\(t\)-norm is a function \(\varphi\colon L\times L\to L\) such that \(\forall x,y,z\in L\), (1) \(x\leq ...

Fuzzy ideals and fuzzy prime ideals of a ring

Fuzzy Sets and Systems, 1991
Firstly, the authors focus on the generalization of the well-known classical property: the union of two ideals of a ring is again an ideal iff one of them is contained in the other. By means of a counterexample it is proven that this property does not hold in general for fuzzy ideals.

On the fuzzy polynomial ideals

Journal of Intelligent & Fuzzy Systems, 2014
In this paper we introduce the notion of a fuzzy polynomial ideal α x of a polynomial ring R[x] induced by a fuzzy ideal α of a ring R, and obtain an isomorphism theorem of a ring of fuzzy cosets of α x .
