Abstract
Let S be a fuzzy semihypergroup. We introduce the notions of fuzzy S-hypersystems over fuzzy semihypergroups and study their elementary properties. We improve fuzzy regular relations and fuzzy strongly regular relations. The fuzzy hyper versions of the fundamental normal homomorphism theorems are obtained, and product and coproduct of fuzzy S-hypersystems are discussed. In addition, we derive some results on crisp S-hypersystems and semihypergroup.
期刊介绍:
Since its launching in 1978, the journal Fuzzy Sets and Systems has been devoted to the international advancement of the theory and application of fuzzy sets and systems. The theory of fuzzy sets now encompasses a well organized corpus of basic notions including (and not restricted to) aggregation operations, a generalized theory of relations, specific measures of information content, a calculus of fuzzy numbers. Fuzzy sets are also the cornerstone of a non-additive uncertainty theory, namely possibility theory, and of a versatile tool for both linguistic and numerical modeling: fuzzy rule-based systems. Numerous works now combine fuzzy concepts with other scientific disciplines as well as modern technologies.
In mathematics fuzzy sets have triggered new research topics in connection with category theory, topology, algebra, analysis. Fuzzy sets are also part of a recent trend in the study of generalized measures and integrals, and are combined with statistical methods. Furthermore, fuzzy sets have strong logical underpinnings in the tradition of many-valued logics.
