Global regularity for minimal sets near a union of two planes
Annales de l'Institut Fourier, Volume 66 (2016) no. 5, p. 2067-2099
We discuss the global regularity of 2 dimensional minimal sets that are near a union of two planes, and prove that every global minimal set in 4 that looks like a union of two almost orthogonal planes at infinity is a cone. The main point is to use the topological properties of a minimal set at a large scale to control its behavior at smaller scales.
On traite la régularité globale des ensembles minimaux 2-dimensionnels qui sont proches d’une union de deux plans, et on démontre que tout ensemble minimal proche d’une union de deux plans presque orthogonaux à l’infini dans 4 est un cône. L’enjeu est de contrôler le comportement d’un ensemble minimal à petite échelle par la topologie à grande échelle.
