Résumé
Abstract

Nous considérons la fonctionnelle de Ginzburg–Landau pour les applications à valeurs dans $R^{N}$ définies dans la boule unité $B^{N} \subset R^{N}$ avec la donnée de tourbillon x au bord $\partial B^{N}$ . En dimension $N \geq 7$ , nous montrons que, pour tout $ε > 0$ , il existe un unique minimiseur global $u_{ε}$ à ce problème ; de plus, $u_{ε}$ est symétrique de la forme $u_{ε} (x) = f_{ε} (| x |) \frac{x}{| x |}$ pour $x \in B^{N}$ .

For $ε > 0$ , we consider the Ginzburg–Landau functional for $R^{N}$ -valued maps defined in the unit ball $B^{N} \subset R^{N}$ with the vortex boundary data x on $\partial B^{N}$ . In dimensions $N \geq 7$ , we prove that, for every $ε > 0$ , there exists a unique global minimizer $u_{ε}$ of this problem; moreover, $u_{ε}$ is symmetric and of the form $u_{ε} (x) = f_{ε} (| x |) \frac{x}{| x |}$ for $x \in B^{N}$ .
