Seminumerical method for tracking multibreathers in Klein-Gordon chains.
We present a method of numerical calculation of multibreathers in Klein-Gordon chains. This method provides in advance the linear stability of the calculated multibreather solutions. We illustrate the method by calculating initial conditions for multibreathers in a chain of coupled Morse oscillators.
