Nous prouvons une nouvelle inégalite sur le jacobien (ou vorticité) associé à l'énergie de Ginzburg–Landau en dimension quelconque, et en donnons des corollaires statiques et dynamiques. Nous présentons ensuite une méthode pour prouver la convergence de flots-gradient associés à une famille d'énergies qui Gamma-convergent vers une énergie limite, que nous appliquons pour établir à l'aide de l'estimée dynamique précédemment obtenue, la loi limite de la dynamique d'un nombre fini de vortex pour le flot (de la chaleur) de Ginzburg–Landau en dimension 2 avec et sans champ magnétique.
We prove a new inequality for the Jacobian (or vorticity) associated to the Ginzburg–Landau energy in any dimension, and give static and dynamical corollaries. We then present a method to prove convergence of gradient-flows of families of energies which Gamma-converge to a limiting energy, which we apply to establish, thanks to the previous dynamical estimate, the limiting dynamical law of a finite number of vortices for the heat-flow of Ginzburg–Landau in dimension 2, with and without magnetic field.
