短脉冲方程中的波破碎

Wave breaking in the short-pulse equation

Yue Liu, Dmitry Pelinovsky, Anton Sakovich

摘要:

在超短脉冲尺度上,给出了描述几个周期波包的短脉冲方程的波破碎的充分条件。分析依赖于短脉冲方程的特征和守恒量的方法,并保持在无限长的线和周期域。给出了周期域中有限时间波破碎的数值例子。

英文摘要:

Sufficient conditions for wave breaking are found for the short-pulse equation describing wave packets of few cycles on the ultra-short pulse scale. The analysis relies on the method of characteristics and conserved quantities of the short-pulse equation and holds both on an infinite line and in a periodic domain. Numerical illustrations of the finite-time wave breaking are given in a periodic domain.
