BIFURCATIONS OF TRAVELING WAVE SOLUTIONS OF INTEGRABLE EVOLUTION EQUATIONS FOR SURFACE WAVES IN DEEP WATER
MO Da-long,LU Liang,GUO Xiu-feng
Abstract:
In this paper, we investigate the traveling wave solutions of a small-aspect-ratio wave equation and an integrable evolution equation for surface waves in deep water. By applying the qualitative theory of differential equations, we analyze the phase portraits of the traveling wave systems and obtain the exact explicit representations of solitary wave solutions.
Key words:  traveling wave solutions  bifurcations of phase portraits  integrable systems  surface waves equations
