A stability result in the localization of cavities in a thermic conducting medium
ESAIM: Control, Optimisation and Calculus of Variations, Tome 7 (2002), pp. 521-565.

We prove a logarithmic stability estimate for a parabolic inverse problem concerning the localization of unknown cavities in a thermic conducting medium Ω in n , n2, from a single pair of boundary measurements of temperature and thermal flux.
