线性弥散激波

Linear Dispersive Shocks

David Smith, Thomas Trogdon, Vishal Vasan

摘要:

我们提出了一个线性色散偏微分方程,它体现了一些定性特征的色散冲击,通常认为只发生在非线性模型。该模型捕捉到了大部分的短时间现象,但偏离了其长时间行为的完全非线性模型。虽然我们目前的讨论仅限于Korteweg-de Vries方程中的色散激波,但我们的工作也很容易扩展到其他高阶色散模型。

英文摘要:

We present a linear dispersive partial differential equation which manifests a number of qualitative features of dispersive shocks, typically thought to occur only in nonlinear models. The model captures much of the short time phenomenon but deviates from the full nonlinear model in its long time behavior. Though we limit our present discussion to dispersive shocks occurring in the Korteweg-de Vries equation, our work extends readily to other higher order dispersive models too.
