Characterizations of ternary semigroups by ,qk -fuzzy ideals

In this paper we have generalized the concepts of ??,??q?-fuzzy ideals, ??,??q?-fuzzy quasi-ideals and ??,??q?-fuzzy bi-ideals by introducing the concepts of ? ? k ?,??q -fuzzy ideals, ? ? k ?,??q -fuzzy quasiideals and ? ? k ?,??q -fuzzy bi-ideals in ternary semigroups and several related properties are investigated. Different characterizations of regular and weakly regular ternary semigroups by the properties of these ideals are given.
