Changing shapes: adiabatic dynamics of composite solitary waves
arXiv:nlin/0411050 · doi:10.1016/j.physd.2004.11.009
Abstract
We discuss the solitary wave solutions of a particular two-component scalar field model in two-dimensional Minkowski space. These solitary waves involve one, two or four lumps of energy. The adiabatic motion of these composite non-linear non-dispersive waves points to variations in shape.
