Invariant Convergence of Double Sequences in Fuzzy Normed Spaces

Abstract

In this study, for double sequences, we defined the notions of invariant convergence and invariant Cauchy double sequences in fuzzy normed spaces. Also, we investigated some properties of invariant convergence and relations between invariant convergence and invariant Cauchy double sequences in fuzzy normed spaces.

Keywords

• Invariant convergence
• double sequences
• fuzzy normed spaces
• invariant Cauchy double sequence
