Abstract:
The main purpose of this thesis is to find the solution of (2 + 1)−
dimensional nonlinear Schr¨odinger equations. The Exp-function method
is applied to find a solution of (2 + 1)−dimensional nonlinear system
of SE. It is shown that the method provides a powerful mathematical
tool for solving nonlinear evolution equations in mathematical physics.
The obtained solution for each results were illustrated by graphical
plots. The obtained results are exactly fit with exact solutions which
solves the complexity of finding the solutions for (2+ 1)−dimensional
NLS
