Uniqueness for an ill-posed parabolic system
[Unicité pour un système parabolique mal-posé]
Comptes Rendus. Mathématique, Volume 349 (2011) no. 21-22, pp. 1161-1165.

Lʼobjectif est de prouver lʼunicité de solution pour un système parabolique mal-posé. Ce résultat sert à établir lʼidentifiabilité pour le problème de detection de sources ponctuelles de pollution organique dans les eaux de surface.

The purpose is the uniqueness for an ill-posed parabolic system. This result enables us to state the identifiability for the problem of detecting pointwise organic pollution sources in surface waters.
