An integrable equation governing short waves in a long-wave model (Document sans référence bibliographique) 2003-03-20Texte intégral en Openaccess : Ref HAL: hal-00266319_v1 Ref Arxiv: physics/0303085 Ref. & Cit.: NASA ADS Exporter : BibTex | endNote Résumé: From a columnar approximation of the Euler equations of an incompressible fluid with surface tension, we derive in the short-wave approximation a new integrable classical 1+1 dimensional field theory for the motion of the surface. Together with a Lorentz invariance,this system has the novel feature of solutions which become multiple valued in finite time. |
