Résumé
Abstract

Si le tenseur de Riemann–Christoffel associé à un champ de classe $𝒞^{2}$ de matrices symétriques définies positives d'ordre trois s'annule sur un ouvert connexe et simplement connexe $Ω \subset ℝ^{3}$ , alors ce champ est celui du tenseur métrique associé à une déformation de classe $𝒞^{3}$ de l'ensemble $Ω$ , déterminée de façon unique à une isométrie de $ℝ^{3}$ près. On établit ici la continuité de l'application ainsi définie, pour des topologies métrisables convenables.

If the Riemann–Christoffel tensor associated with a field of class $𝒞^{2}$ of positive definite symmetric matrices of order three vanishes in a connected and simply connected open subset $Ω \subset ℝ^{3}$ , then this field is the metric tensor field associated with a deformation of class $𝒞^{3}$ of the set $Ω$ , uniquely determined up to isometries of $ℝ^{3}$ . We establish here that the mapping defined in this fashion is continuous, for ad hoc metrizable topologies.
