Exp-function method for solving the schr dinger and improved eckhaus equations

الملخص EN

In this research, the exp-function method has been used to find travelling wave solutions of Schr dinger and improved Eckhaus Equations.

The solution procedure of this method, by the help of symbolic computation of Maple or Matlab, is of utter simplicity.

The exp-function method is a powerful and straightforward mathematical tool to solve the nonlinear equations in mathematical physics.
