Bifurcations and exact traveling wave solutions for the regularized Schamel equation

open access: yesOpen Mathematics, 2021
In the present paper, we focus on studying the bifurcations and the traveling wave solutions (TWSs) for the regularized Schamel equation. Based on the bifurcation method of a dynamical system, a complete phase portrait analysis is given in various ...
