The problem of detecting corrosion by electric measurements revisited
Résumé
We establish a logarithmic stability estimate for the problem of detecting corrosion by electric measurements. We propose a proof based on an adaptation of the method initiated in [BCJ]. Roughly speaking, it consists in estimating a lower bound of the local $L^2$-norm at the boundary of the solution of the boundary value problem used in modeling the problem of detection corrosion by electric measurements.
