HY2W01 - Modulation theory and dispersive shock waves

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).
