Abstract
An approximately globally convergent numerical method proposed by Beilina and Klibanov for a coefficient inverse problem related to the hyperbolic equation is studied. While the global convergence of this method has been proved for the
case, in
case, it was proved only partially. The last case is of an interest, since it was demonstrated that the
version of this method works well for a set of experimental data. In this paper, a complete proof of convergence of this method in
is presented.
