We discuss an exact reconstruction algorithm for time expanding semi-algebraic sets given by a single polynomial inequality. The theoretical motivation comes from the classical L-problem of moments, while some possible applications to 2D fluid moving boundaries are sketched. The proofs rely on an adapted co-area theorem and a Hankel form minimization.

Nous présentons un algorithme de reconstruction exacte pour des domaines sémi-algèbriques croissants en temps, qui sont donnés par une seule inegalité polyno ^miale. La motivation théoretique vient du L-problème classique des moments, et nous esquissons une application possible aux fluides 2D avec des frontières mobiles. Les démonstrations sont basées sur le théorème de la co-aire et utilisent aussi la minimization d’une forme de Hankel.
