将区间值模糊集和D[0,1]上的t-模£应用于格蕴涵代数的滤子理论,引入格蕴涵代数的区间值£-模糊(关联、正关联)滤子的概念,给出了它们的等价刻画,研究了它们之间的关系。
Interval-valued fuzzy set and a t-norm on D[O, 1] are applied to the filter theory of lattice implication algebras. The concepts of interval-valued £--fuzzy (implicative, positive implicative) filters with respect to a t-norm £- on D [ O, 1 ] are proposed, some equivalent characterizations of these generalized fuzzy filters are derived and the relations among them are studied.
