λ-statistical convergence of double sequences in fuzzy n-normed spaced

This thesis consists of seven chapters. The first chapter is devoted to the introduction. In chapter two, basic definitions and theorems are given. In chapter three, information on statistical convergence is given. In chapter four, convergence in n-normed spaces, statistical convergence and λ-statistical convergence are explained. In chapter five, convergence in double sequences, statistical convergence and λ-statistical convergence are explained. In chapter six, convergence in fuzzy normed spaces, statistical convergence and λ-statistical convergence are explained. In chapter seven, The results were obtained with the help of the information explained in the previous sections.
