【Abstract】 This paper firstly introduces t - norms Ton lattice interval sets [L], by t - norms T on complete distributive lattice L and then defines the ■ - type lattice interval value fuzzy subgroup and ■ - type lattice interval value fuzzy normal subgroup. Finally, it studies some properties of this subgroup. Consequently,it obtaines the characterizations of them.更多还原
