In a double sine-Gordon system the internal oscillations of a solitary wave solution can be viewed as normal modes in a number of sine-Gordon 2π-kinks and the ratio between the frequencies can be predicted. For three 2π-kinks this ration is √3.

Abstract
In a double sine-Gordon system the internal oscillations of a solitary wave solution can be viewed as normal modes in a number of sine-Gordon 2π-kinks and the ratio between the frequencies can be predicted. For three 2π-kinks this ration is √3.File in questo prodotto:
