Abstract The partial dierential equitations (PDEs) are used to describe a wide range of phenomena such as sound, heat, diusion, electrostatics, electrodynamics, uid dynamics, exibility, gravity, and quantum mechanics. These equations play a central role in the modeling of many chemical, physical and biological phenomena. Therefore, the importance of getting exact and soliton solutions to PDE equations in mathematics is an important problem that needs to many studies. So, in this thesis, we present some of the methods recently used to solve nonlinear partial dierential equations (NPDEs) that represent some of the physically relevant systems in applied mathematics, applied physics, especially in optics, uids and a few works in electronics. Some problems were also presented and solutions were found to be ill, whether exact or soliton solutions or both. |
