Some convergence types in double sequences of real-valued functions

In the first chapter of this thesis that consists of three chapters, we give some fundamental definitions and theorems which will be used in the later chapters. In the second chapter; Pointwise, uniform and statistical convergence for double sequences of real-valued functions are given. In the third chapter; Strongly Cesàro convergence and Lacunary statistical convergence of double sequences of real-valued functions are given. Key Words: Double sequence, Functional double sequence, Double natural density, Pointwise statistical convergence, Strongly Cesàro convergence, Lacunary statistical convergence.
