to start with, having employed transformation wave, some nonlinear partial differential equations have been converted into an ode. then, using the infinite series method for equations with similar linear part, the researchers have earned the exact soliton solutions of the selected equations. it is required to state that the infinite series method is a well-organized method for obtaining exact s...

This paper studies the phi-four equation that arises in Quantum Mechanics. The topological 1-soliton solution or kink solution is obtained by the ansatz method. The bifurcation analysis is then subsequently carried out and several other solutions are retrieved from the analysis. These solutions include the solitary wave solutions, periodic waves and periodic singular waves. The constraint condi...

This paper, for the first time ever, proposes a Laplace-like integral transform, which is called as He-Laplace its basic properties are elucidated. The homotopy perturbation method coupled with this new transform becomes much effective in solving fractal differential equations. Phi-four equation He?s derivative used an example to reveal main merits of present technology.

This paper examines two methods for solving the nonlinear fractional Phi-four problem with variable coefficients. One of distinct states Klein–Gordon model yields equation. It is also used to simulate kink and anti-kink solitary wave connections that have recently emerged in biological systems nuclear particle physics. The approaches are being suggested consist Yang transform, homotopy perturba...
