The problem of detecting corrosion by an electric measurement revisited [PDF]

open access: yes, 2015
We establish a logarithmic stability estimate for the problem of detecting corrosion by a single electric measurement. We give a proof based on an adaptation of the method initiated in \cite{BCJ} for solving the inverse problem of recovering the surface ...
