Abstract
We present evidence that the autonomous sine-Gordon system, subject to time-independent boundary conditions, gives rise to two fundamental families of stable dynamical configurations : particle (soliton) excitations and linear mode-like oscillations. The two dynamical configurations are clearly separated by a threshold value of a boundary parameter. The competition between these two basic dynamic families gives rise to chaotic motion of solitons and unstable oscillatory patterns for a threshold value of a boundary parameter.
