Chaotic Motions in an Oscillatory Soliton Lattice

- 論文の詳細を見る
Weak interactions of the oscillatory solitary waves for the fifth order Korteweg-deVries equation are investigated in terms of a soliton lattice model. Numerical solu-lions of the three pulse periodic system show two types of chaotic changes of theinfer-pulse distances, depending on the total periodicity length. As an increase of thedeviation of the initial value from a fixed point with center-like singularity, periodicmotions show frequency down-shifts and lead to chaotic behaviour. A bounded mo-tion associated with one stable fixed point involves chaotic behaviour that is an ir-regular manifestation of modulation. Another motion associated with three stablefixed points involves chaotic behaviour ascribed to an irregular meandering amongthese fixed points. Observed frequency down-shifts are explained in terms of a pertur-bation analysis,
