On reconstruction of Riemannian manifold via boundary data: theory and plan of numerical testing

The paper deals with an inverse problem of reconstruction of a Riemannian manifold via its boundary data. This problem has been solved by the boundary control method, whereas at the moment there are a few variants of solving it. In the paper, one more version of the procedure, which recovers the manifold via the scalar spectral or dynamical data, is proposed. This version is a simplest one in regard to the devices in use: we do not enlist geometrical optics, polar representation of operators, etc, but get by with a controllability property of the relevant dynamical system. With no substantial changes, this version is applicable to more the complicated (vector) problem of electrodynamics for the Maxwell system. Simplicity of the proposed procedure provides additional chances for its numerical realizability. At the end of the paper, a plan of numerical experiment is discussed. To draw attention to such new options is one of the main aims of the paper. Bibl. 9 titles.
