چکیده | ||
i.p.s. hypergroups are canonical hypergroups such that $[\forall(a,x),a+x\ni x]\Longrightarrow[a+x=x].$ i.p.s. hypergroups were investigated in [1], [2], [3], [4] and it was proved that if the order is less than 9, they are strongly canonical (see [13]). In this paper we obtain the sequences of fuzzy sets and of join spaces determined (see [8]) by all i.p.s. hypergroups of order seven. For the meaning of the hypergroups iH and the notations, see [7], [8]. | ||
