We prove the existence and the invariance of a Gibbs measure associated to the defocusing sub-quintic Nonlinear Schrödinger equations on the disc of the plane . We also prove an estimate giving some intuition to what may happen in dimensions.
On démontre l’existence et l’invariance d’une mesure de Gibbs par le flot de l’équation de Schrödinger non linéaire posée sur le disque du plan . On démontre également une estimée qui donne une idée de ce qui pourrait arriver en dimension .
Keywords: Nonlinear Schrödinger, eigenfunctions, dispersive equations, invariant measures
