On Krull′s intersection theorem of fuzzy ideals

International 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.

On fuzzy subbundles of vector bundles

International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 40, Page 2553-2565, 2003., 2003
This paper considers fuzzy subbundles of a vector bundle. We define the operations sum, product, tensor product, Hom, and intersection of fuzzy subbundles and in each case, we characterize the corresponding flag of vector subbundles. We then propose two alternative definitions of integrability on fuzzy subbundles of a given type and discuss their ...

On an equivalence of fuzzy subgroups III

International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 36, Page 2303-2313, 2003., 2003
This paper is the third in a series of papers studying equivalence classes of fuzzy subgroups of a given group under a suitable equivalence relation. We introduce the notion of a pinned flag in order to study the operations sum, intersection and union, and their behavior with respect to the equivalence.

Doubt fuzzy BCI‐algebras

International Journal of Mathematics and Mathematical Sciences, Volume 30, Issue 1, Page 49-56, 2002., 2002
The aim of this note is to introduce the notion of doubt fuzzy p‐ideals in BCI‐algebras and to study their properties. We also solve the problem of classifying doubt fuzzy p‐ideals and study fuzzy relations on BCI‐algebras.

On Covering Prosperities via Neutrosophic e‐Open Set in Neutrosophic Topological Space

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This research presents and explores a novel category of compactness in neutrosophic topological spaces (NTSs), termed neutrosophic e‐compact and neutrosophic locally e‐compact. This category is positioned within the frameworks of neutrosophic δ‐semicompactness and neutrosophic δ‐precompactness, while also encompassing neutrosophic β‐compactness.

A new view of relationship between atomic posets and complete (algebraic) lattices

Open Mathematics, 2017
In the context of the atomic poset, we propose several new methods of constructing the complete lattice and the algebraic lattice, and the mutual decision of relationship between atomic posets and complete lattices (algebraic lattices) is studied.

On generalized fuzzy strongly semiclosed sets in fuzzy topological spaces

International Journal of Mathematics and Mathematical Sciences, Volume 30, Issue 11, Page 651-657, 2002., 2002
We introduce the concept of generalized fuzzy strongly semiclosed, generalized fuzzy almost‐strongly semiclosed, generalized fuzzy strongly closed, and generalized fuzzy almost‐strongly closed sets. In the light of these definitions, we also define some generalizations of fuzzy continuous functions and discuss the relations between these new classes of

Weak-hyperlattices derived from fuzzy congruences

Discussiones Mathematicae - General Algebra and Applications, 2017
In this paper we explore the connections between fuzzy congruence relations, fuzzy ideals and homomorphisms of hyperlattices. Indeed, we introduce the concept of fuzzy quotient set of hyperlattices as it was done in the case of rings [19].

Mathematical insights into interval solutions of fuzzy relation inequalities for effective Information resource sharing in business education

Applied Mathematics in Science and Engineering, 2023
To examine the connectivity of educational and business institution networks and assess their resource accessibility, we have employed min-max fuzzy relation systems.
