A geometric formulation of Bäcklund transformations between wavelike Monge-Ampere equations (for one function of two variables) leads to an overdetermined PDE system for the equations defining the ...

Surface Plasmon Polaritons (SPPs) are electromagnetic waves that propagate along metal/dielectric interfaces. They have many interesting properties such as wavelength reduction and spatial confinement ...

Abstract: The talk is aimed at presenting an overview of recent results on the development and application of Whitham modulation theory for two-dimensional nonlinear evolution equations, focusing ...
