- In 1965 A.N. Tikhonov, the founder of the theory of Ill-Posed and Inverse Problems, has posed an coefficient inverse problem of the recovery of the unknown electric conductivity coefficient from measurements of the back reflected electrical signal. In the geophysical application targeted by Tikhonov, this coefficient depends only on the depth and characterizes the electrical conductivity of the ground. The goal of this paper is to construct for this problem a version of the globally convergent convexification numerical method for this problem. In this version, the viscosity term is introduced. A Carleman estimate allows to prove global convergence of this method.
