Abstract
The Korteweg-de Vries (Kdv) equation has been generalized by Rosenau and Hyman [7] to a class of partial differential equations (PDEs) which has solitary wave solution with compact support. These solitary wave solutions are called compactons
Compactons are solitary waves with the remarkable soliton property, that after colliding with other compactons, they reemerge with the same coherent shape. These particle like waves exhibit elastic collision that are similar to the soliton interaction associated with completely integrable systems. The point where two compactons collide are marked by a creation of low amplitude compacton-anticompacton pair. These equations have only a finite number of local conservation laws
In this paper, an implicit finite difference method and a finite element method have been developed to solve the K(3,2) equation. Accuracy and stability of the methods have been studied. The analytical solution and the conserved quantities are used to assess the accuracy of the suggested methods. The umerical results have shown that this compacton exhibits true soliton behavior.
