Nous présentons de nouveaux résultats concernant l'étude asymptotique du flot de la chaleur pour l'énergie de Ginzburg–Landau. En particulier, nous montrons que, lorsque le paramètre ε tend vers 0, la vorticité évolue selon un mouvement par courbure moyenne, dans un sens faible introduit par Brakke. Notre seule hypothèse concerne une borne naturelle portant sur l'énergie de la condition initiale. Dans certains cas, nous montrons également la convergence vers un mouvement par courbure moyenne dans un sens plus fort dû à Ilmanen.
We present some new results for the asymptotic behavior of the complex parabolic Ginzburg–Landau equation. In particular, we establish that, as the parameter ε tends to 0, vorticity evolves according to motion by mean curvature in Brakke's weak formulation. The only assumption we make is a natural energy bound on the initial data. In some cases, we also prove convergence to enhanced motion in the sense of Ilmanen.
