RETRACTED ARTICLE: sp- Closedness and sp- convergent sequences in IFMS and its generalization to L-fuzzy metric space

The aim of the present article is to introduce the concepts of s p - convergent sequence in generalized intuitionistic fuzzy metric spaces, i.e., L -fuzzy metric spaces and analyze relations of convergence, s p - convergence, s ∞ - convergence and s t - convergence in L -fuzzy metric spaces. Further, we examine s p - convergence, s ∞ - convergence and s t - convergence using the subsequence of convergent sequence for above-stated spaces. We finally define s p - closed sets, s ∞ - closed sets and s t - closed sets in intuitionistic fuzzy metric spaces and investigate relations of them.
