Whitham-Broer-Kaup Systems in Multi-dimensions: Quantum and Resonant NLS Connections
Abstract
An overview is presented of quantum and resonant nonlinear Schr\"odinger equation links to Whitham-Broer-Kaup type systems. A novel n+1-dimensional extension of the Whitham-Broer-Kaup hydrodynamic system is constructed with connection to an equivalent multi-dimensional resonant NLS equation. Hybrid Ermakov-Painlev\'e II and associated Painlev\'e XXXIV integrable similarity reductions are derived.
