Abstract

We consider a nonlinear third order dispersive equation which models the motion of a vortex filament immersed in an incompressible and inviscid fluid occupying the three dimensional half space. We prove the unique solvability of initial–boundary value problems as an attempt to analyze the motion of a tornado.

Résumé

On considère une équation non linéaire dispersive de troisième ordre qui modélise le mouvement d'un filament tourbillonnaire immergé dans un fluide incompressible et non visqueux occupant le demi-espace en trois dimensions. Nous prouvons la solvabilité des problèmes aux limites comme une tentative pour analyser le mouvement d'une tornade.
