On Permutable and Mutually Permutable Fuzzy Groups

Hassan Naraghi


In this paper, we define permutable and mutually permutable fuzzy subgroups of a group. Then we study their relation with permutable and mutually permutable subgroups of a group. We also study some properties of fuzzy quasinormal subgroup. We define superfuzzy subset of a fuzzy subset and we also study some properties of superfuzzy subset of a fuzzy subset.


permutable fuzzy subgroup, mutually permutable fuzzy subgroup, fuzzy quasinormal subgroup, superfuzzy subset.
