Investigation of oscillation behavior of solutions of first order delay difference equations

This Msc thesis consists of five parts. In the first chapter, general information about de- lay difference equations and the literature summary of researches are given. In the second chapter, general definitions and theorems concerning delay difference equations are gi- ven. In the third chapter, the oscillation conditions of the solutions of constant coefficient- constant delays and variable coefficient-constant delay difference equations mentioned are given. In the fourth chapter, findings and discussion sections and finally in the fifth chapter conclusion is included.
