On Deferred Statistical Convergence of Sequences in Neutrosophic Normed Spaces

In this paper, we introduce the notion of deferred sta- tistical convergence in the neutrosophic normed spaces as an ex- tension of statistical convergence, λ-statistical convergence, and la- cunary statistical convergence. We investigate a few fundamental properties of the newly introduced notion. Finally, we introduce the concept of deferred statistical Cauchy sequence and show that deferred statistical Cauchy sequences are equivalent to deferred sta- tistical convergent sequences in the neutrosophic normed spaces.
