Up to isometries, a deformation is a continuous function of its metric tensor
[Aux isométries près, une déformation est une fonction continue de son tenseur métrique]
Comptes Rendus. Mathématique, Volume 335 (2002) no. 5, pp. 489-493.

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 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 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 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 3 . We establish here that the mapping defined in this fashion is continuous, for ad hoc metrizable topologies.
