Abstract: In this study, we have investigated the concepts of lacunary summable, lacunary statistical convergence and lacunary statistically Cauchy sequence for double sequences in fuzzy normed spaces. Also, we have investigated some properties and relationships between these concepts.

Keywords: Double sequences, statistical convergence, fuzzy numbers, fuzzy normed spaces, lacunary sequences
