Generalized difference sequence spaces defined by Orlicz function

In the first chapter of this thesis that consists of five chapters, we give some fundamentaldefinitions and theorems which will be used in the later chapters and examine N- functionsin the special class of convex functions and some properties of Young inequalities.In the second chapter, we give Orlicz sequence space, lM and lM (p) sequence spaces.In the third chapter, we give natural density and relation between statistically convergenceand strongly Cesaro convergence.In the fourth chapter, we give the connection between generalifzed difference sequencespaces and ?m- statistically convergence.In the fifth chapter, we give some results about generalized diference sequence spaceswhich is defined using Orlicz functions and ?m- statistically convergence.
