Sequences of fuzzy numbers and their statistical convergence

In the first cahpter of this thesis that consists of two chapters, we give some fundamental definitions and theorems which will be used in the next chapter and examine some properties of statistical convergence. In the second chapter we give the consepts of fuzzy set, fuzzy number and the sequences of fuzzy number and investigate that statistical convergence and almost lacunary statistical convergence of the sequences of fuzzy number. Key Words: Fuzzy set, Fuzzy number, Sequence of fuzzy numbers, Statistical convergence, Lacunary sequence,
