五次非线性Schrodinger方程的能量传递模型和大周期边值问题

Energy transfer model and large periodic boundary value problem for the quintic nonlinear Schrodinger equations

Hideo Takaoka

摘要:

研究了一维五次非线性薛定谔方程的动力学和线性振子与非线性相互作用态之间的能量交换。Grebert和Eschann证明了在四种Fourier模式下存在初始解,证实了波能守恒交换。在多个傅立叶模式中捕获多个共振,我们模拟了长周期波中类似的能量交换。

英文摘要:

We study a dynamics and energy exchanges between a linear oscillator and a nonlinear interaction state for the one dimensional, quintic nonlinear Schrodinger equation. Grebert and Thomann proved that there exist solutions with initial data built on four Fourier modes, that confirms the conservative exchange of wave energy. Captured multi resonance in multiple Fourier modes, we simulate a similar energy exchange in long-period waves.
