Full Description


This work deals with some inverse problems of mathematical physics. It introduces some new methods for studying inverse problems and gives obtained results, which are related to the conditional well posedness of the problems. The main focus lies on time-domain inverse problems for hyperbolic equations. The final chapter deals with the kinetic transport equation.
