A-statistical relative korovkin type approximation theorem on modular spaces

This thesis consists of three chapters. The first chapter has been devoted for the introduction. In the second chapter, the concepts of summability, statistical convergence, and statistical convergence have been recalled. Examples and some results concerning these concept have been given. In the first section of the third chapter, the concept of relative modular convergence has been given. In the second section, using this convergence, Korovkin type theorem has been studied. In the third section, statistical relative modular convergence has been introduced and in the fourth section, using this definition, statistical relative Korovkin type theorem has been investigated through this definition. Finally, an example has been given which provides this theorem but does not provide the Korovkin type theorem in modular spaces.
