On the fuzzy convergence of sequences in a fuzzy normed linear space

Gil-Seob Rhie, In-Ah Hwang

Open full text 2 citations

Abstract

In this paper, we introduce the notions of a fuzzy convergence of sequences, fuzzy Cauchy sequence and the related fuzzy completeness on a fuzzy normed linear space. And we investigate some properties relative to fuzzy normed linear spaces. In particular, we prove an equivalent conditions that a fuzzy norm defined on a ordinary normed linear space is fuzzy complete.
