[Une méthode d'accélération de type Aitken appliquée à la reconstruction de données frontières manquantes sur le problème de Cauchy–Helmholtz]
Comptes Rendus. Mathématique, Volume 348 (2010) no. 1-2, pp. 93-97.

Cette Note concerne le problème mal-posé de Cauchy–Helmholtz. Ce problème est interprété en terme d'équation d'interface qu'on résout via une méthode d'Aitken–Schwarz. Des essais numériques illustrent l'efficacité de cette méthode.

This Note is concerned with the severely ill-posed Cauchy–Helmholtz problem. This Cauchy problem being rephrased through an “interfacial” equation, we resort to an Aitken–Schwarz method for solving this equation. Numerical trials highlight the efficiency of the present method.
