Abstract: The theory of planar dynamical systems is used to study the dynamical behaviour of the travelling wave solutions of a nonlinear wave equations of KdV type. In different regions of the parametric space, sufficient conditions to guarantee the existence of solitary wave solutions, periodic wave solutions, kink and anti-kink wave solutions are given. All possible exact explicit parametric representations are obtained for these waves.
- solitary wave solution /
- periodic wave solution /
- kink wave and anti-kink wave solutions /
- smooth and non-smooth periodic wave
