The Galerkin Method

In this paper, a numerical method is proposed to approximate the solution of the nonlinear damped generalized regularized long-wave (DGRLW) equation with a variable coefficient. The method is based upon Ritz Legendre multiwavelet approximations. The properties of Legendre multiwavelet are first presented. These properties together with the Galerkin method are then utilized to reduce the nonlinear DGRLW equation to the solution of algebraic equations. Illustrative examples are included to demonstrate the validity and applicability of the technique.

Regularized Long Wave Equation

The generalized regularized long wave equation is very important that can be applied in the field of physics,science and technology. Some authors have put forward many different numerical method, but the precision isnot enough high. In this paper, we will illustrate the high-precision numerical method to solve the generalizedregularized long wave equation. Three numerical examples are studied to demonstrate the accuracy of thepresent method. Results obtained by our method indicate new algorithm has the following advantages: smallcomputational work, fast convergence speed and high precision.
