The Comparison Study of Hybrid Method with RDTM for Solving Rosenau-Hyman Equation

Application of semi-analytical methods for solving the Rosenau–Hyman equation

In this work, the homotopy perturbation method (HPM), variational iteration method (VIM) and Adomian decomposition method (ADM) are applied to solve the Rosenau–Hyman equation. We used the initial condition ( u(x, 0) = −83 cos 2 ( x 4 )) for aforementioned methods. Numerical solutions obtained by these methods are compared with the exact solutions, revealing that the obtained solutions are of h...

Self-similar radiation from numerical Rosenau-Hyman compactons

The numerical simulation of compactons, solitary waves with compact support, is characterized by the presence of spurious phenomena, as numerically-induced radiation, which is illustrated here using four numerical methods applied to the RosenauHyman K(p, p) equation. Both forward and backward radiations are emitted from the compacton presenting a self-similar shape which has been illustrated gr...

Sinc operational matrix method for solving the Bagley-Torvik equation

The aim of this paper is to present a new numerical method for solving the Bagley-Torvik equation. This equation has an important role in fractional calculus. The fractional derivatives are described based on the Caputo sense. Some properties of the sinc functions required for our subsequent development are given and are utilized to reduce the computation of solution of the Bagley-Torvik equati...
