[Analyse de Lyapunov et stabilisation vers l'état d'équilibre pour les solutions des equations de Navier–Stokes compressibles unidimensionnelles]
Dans cette Note, nous établissons de nouvelles estimées pour le comportement asymptotique en temps des solutions des équations unidimensionnelles de Navier–Stokes pour un fluide compressible barotropique, associées à des conditions aux limites homogènes de Dirichlet, pour de larges conditions initiales, sous l'influence de larges forces externes telles que la densité stationnaire peut s'annuler : un problème fortement singulier. Comme conséquence nous apportons une réponse nouvelle à la question du taux de convergence.
In this Note, we establish new estimates for the long time behavior of the solutions to the Navier–Stokes Equations for a compressible barotropic fluid in 1D, with homogeneous Dirichlet boundary conditions, with large initial data, and under the influence of a large mass force in the case when the stationary density admits vacua: a highly singular problem. As a consequence we bring new answers to the question of the stabilizing rate of convergence.
