Abstract Mathematical modeling of real-life problems creates dierent types of dierential equations that aect an important topics not only in mathematics but also in physics, engineering and economics and the importance of studies of dierential equations in pure mathematics lies in studying the existence of their solutions and their uniqueness. There are many research papers concerned with studying the existence of solution of non- linear dierential equations. Our aim in this thesis is to study the existence and uniqueness of the solutions of some nonlocal problems. This thesis is organized in three chapters and appendix as follows. |
