Fuzzy relations on the same domain are classified according to the equality of families of cut sets. This equality of fuzzy relations is completely characterized, not only for un...
In this paper, we introduce four kinds of rough approximations for a given intuitionistic fuzzy set. Keywords Fuzzy set, Intuitionistic Fuzzy Set, Rough Approximations
Abstract. We prove some results related to the problem of blowing up the power set of the least measurable cardinal. Our forcing results improve those of [1] by using the optimal h...
In this paper, the notion termed a "nonstationary fuzzy set" is introduced, and the concept of a perturbation function that is used for generating nonstationary fuzzy set...
