A study of bifurcation parameters in travelling wave solutions of a damped forced korteweg de vries-kuramoto sivashinsky type equation

In this work, we consider an ordinary differential equation obtained from a damped externally excited Korteweg de Vries-Kuramoto Sivashinsky (KdV-KS) type equation using traveling coordinates. We also include controls and delays and use an asymptotic perturbation method to analyze the sta- bility of the traveling wave solutions. The existence of bounded solutions is presented as well. We consider the primary resonance defined by the detun- ing parameter. External-excitation and frequency-response curves are shown to exhibit jump and hysteresis phenomena (discontinuous transitions between two stable solutions) for the KdV-KS type equation. We have obtained the existence of the bounded solutions of the system obtained from an ordinary differential equation associated with the KdV-KS equation and also show the global stability for a special case when there is no external force.
