Chengyi Zhang · Journal of Hainan Normal University · 2011
In this paper, the interval-valued intuitionistic fuzzy subgroup are studied.And the concept of the interval-valued intuitionistic fuzzy normal subgroup are introduced.Then,we study the interval-valued intuitionistic fuzzy subgroup and the interval-valued intuitionistic fuzzy normal subgroup by nested sets.
