Hyperstructures and fuzzy sets endowed with two membership functions
Finite hyperstructures associated with fuzzy sets endowed with two membership functions are studied. In general, these hyperstructures are commutative hypergroups, but not join spaces. The paper introduces conditions so that the considered hypergroups have also this property, and examples of their fuzzy subhypergroups are given. Two sequences of join spaces and fuzzy sets associated with a finite hypergrupoid are studied using fuzzy sets endowed with two membership functions.
