Abstract:
The Variational Iteration Method (VIM) is a useful method for solving physics
and engineering problems, especially linear and nonlinear of differential equations. In
VIM, a correction function is constructed by a general Lagranges multiplier which
can be identified via a variational theory. The solutions computed by VIM are
analytical solutions.
In this thesis, we apply VIM for solving systems of Korteweg-de Vries. Two
theorems for convergences of the method are presented. The symbolic computation
of VIM to solve the system is computed by Maple programs. For more efficiency,
both theorems of convergence which already included in the programs are given in
detail and how to converge of the solutions for Korteweg-de Vries.
