Schauder Basis, Separability, and Approximation Property in Intuitionistic Fuzzy Normed Space

Abstract

We define and study the concepts of Schauder basis, separability, and approximation property in intuitionistic fuzzy normed spaces and establish some results related to these concepts. We also display here some interesting examples by using classical sequence spaces ${\ell }_p(1\le p\le \infty )$.
