  • The KdV hierarchy in optics 

    Horsley, SAR (IOP Publishing: Hybrid Open Access, 2016-07-20)
    There is a well explored relationship between quantum mechanical scattering from a potential and the Korteweg–de Vries (KdV) equation of fluid dynamics: if the potential is ‘evolved’ according to the KdV equation then it ...
