Stability Analysis for Some Nonlinear Fifth-order Equations

Abstract

The main purpose of this work is to obtain many travelling wave solutions for general Kaup-Kuperschmidt (KK), general Lax, general Sawada-Kotera (SK) and general Ito equations with the extended direct algebraic method. The stability of these solutions and the movement role of the waves by sketching the graphs of the exact solutions are analyzed.
