Fuzzy join n-ary spaces and fuzzy canonical n-ary hypergroups

We extend here the fuzzy approach of algebraic structures to the context of fuzzy n-ary systems. We introduce the notions of a fuzzy join n-ary space and of a fuzzy canonical n-ary hypergroup, which are generalizations of join spaces and canonical hypergroups. We find some properties of them and a characterization of fuzzy canonical n-ary hypergroups, using fuzzy join n-ary spaces.
