摘要:

对具有中长波型非定域性的2+1维可积系统进行了分类。建立了与2+1维水袋系统的链接。本文构造的可积系统的降维方法,给出了描述剪切流中长非线性波传播的流体动力学方程的色散正则化。

英文摘要:

We classify 2+1 dimensional integrable systems with nonlocality of the intermediate long wave type. Links to the 2+1 dimensional waterbag system are established. Dimensional reductions of integrable systems constructed in this paper provide dispersive regularisations of hydrodynamic equations governing propagation of long nonlinear waves in a shear flow with piecewise linear velocity profile (for special values of vorticities).
