Based on the definition of implication-based fuzzy subgroup of a finite group given by Yuan, implication-based T-fuzzy subgroup and implication-based T-normal fuzzy subgroup of a finite group is defined. Some properties of them are proved in this paper. Also T − product,Ṫ − product and T ′ − product of these implication-based T-fuzzy subgroups of a finite group are defined and its properties are discussed.
