Résumé

The asymptotic behavior of the solutions for a non-isothermal model in superfluidity is studied. The model describes the transition between the normal and the superfluid phase in liquid He by means of a non-linear differential system, where the concentration of the superfluid phase satisfies a non-isothermal Ginzburg-Landau equation. Starting from an existence and uniqueness result known for this problem, the system is proved to admit a Lyapunov functional. This allows to obtain existence of the global attractor which consists of the unstable manifold of the stationary solutions. [DOI: 10.1685/CSC09200] About DOI
