SOME TOPOLOGICAL CONCEPTS VIA LEVEL SUBSETS OF A FUZZY SUBSET
The work aims at presenting fuzzy accumulation point of an a-level subset of a fuzzy topological space without any recourse to fuzzy point or cluster fuzzy set. Using this definition, it also studies the closure property of the a-level subsets of a fuzzy topological space and related properties. Besides, a property of convex combination stated by [12] is proven.
