Fermatean fuzzy semi-prime ideals of ordered semigroups

open access: yesTopological Algebra and its Applications, 2023
Fermatean fuzzy sets (FFSs) are invented to resolve the underlying limitations of intuitionistic fuzzy sets and Pythagorean fuzzy sets. The major goal of this study is to introduce Fermatean fuzzy semi-prime ideals of ordered semigroups.

On topological structures of fuzzy parametrized soft sets [PDF]

open access: yes, 2014
In this paper, we introduce the topological structure of fuzzy parametrized soft sets and fuzzy parametrized soft mappings. We define the notion of quasi-coincidence for fuzzy parametrized soft sets and investigated basic properties of it.

Fuzzy soft set approach to ideal theory of regular AG-groupoids

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
This paper aims to apply fuzzy sets and soft sets in combination to investigate algebraic properties of regular AG-groupoids. We initiate (∈γ; ∈γ qδ)-fuzzy soft left ideals (right ideals, bi-ideals and quasi-ideals) over AG-groupoids and explore some ...

On Krull′s intersection theorem of fuzzy ideals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 4, Page 251-262, 2003., 2003
We deal with Krull′s intersection theorem on the ideals of a commutative Noetherian ring in the fuzzy setting. We first characterise products of finitely generated fuzzy ideals in terms of fuzzy points. Then, we study the question of uniqueness and existence of primary decompositions of fuzzy ideals.

Interval-Valued Fuzzy Soft Graphs

open access: yesTopological Algebra and its Applications, 2017
In this paper, we combine concepts of interval-valued fuzzy soft sets and graph theory. Then we introduce notations of interval-valued fuzzy soft graphs and complete interval-valued fuzzy soft graphs.
