(λ,μ)-反模糊粗糙子群

(λ,μ)-anti-fuzzy rough subgroup

引入(λ,μ)-反模糊子群与(λ,μ)-反模糊正规子群的概念,并研究了它们的基本性质。在此基础上,通过定义新的同余关系给出了(λ,μ)-反模糊粗糙子群与(λ,μ)-反模糊粗糙正规子群的概念,并刻画了它们的特征性质。

The definitions of（ λ,μ） anti-fuzzy subgroup and（ λ,μ） anti-fuzzy normal subgroup were introduced first and their properties were discussed. Then based on the newcongruence relation defined from（ λ,μ） anti-fuzzy normal subgroup,the concepts of（ λ,μ） anti-fuzzy rough subgroup and（ λ,μ） anti-fuzzy rough normal subgroup were defined,and some properties were researched.
