Kinds of t-fuzzy Filters of Fuzzy Lattices

AbstractThe starting point of this work comes from the results obtained by Inheung Chon in his paper “Fuzzy partial order relations and fuzzy lattices”. In this way, some characterizations of filters and prime filters are given. Also, we characterize fuzzy -filters and fuzzy prime -filters using their -cuts. Finally, we give necessary and sufficient conditions under which a fuzzy set is a prime -filter, presenting the notion of fuzzy lattices isomorphism.
