Abstract

In this paper we study the structure of certain level set of the Ginzburg-Landau functional which has similar topology with the configuration space. As an application, we generalize Almeida-Bethuel's result on multiplicity of solutions for the Ginzburg-Landau equation.

Résumé

On étudie la structure de certains ensembles de niveau de la fonctionnelle du type Ginzburg-Landau qui ont des topologies similaires à celles de l’espace de configuration. Comme application, on généralise le résultat d’Almeida-Bethuel sur la multiplicité des solutions des équations de G-L.
