Mathematical programming for positive solutions of ill-conditioned inverse problems,the lost information by making use of such a priori constraints as positivity and known moments. This is achieved by the method of quadratic programming, with a choice of optimisation criteria studied.

Inverse 3D acoustic and electromagnetic obstacle scattering by iterative adaptation,roved using an iteration scheme to adapt the internal surface . by exploiting information on the reconstruction . of the previous step. The adaptation algorithm yields significant improvements on ., provided a reasonable first reconstruction may be obtained.

,Generalizations of Karp’s theorem to elastic scattering theory,Karp’s theorem states that if the far field pattern corresponding to the scattering of a time-harmonic acoustic plane wave by a sound-soft obstacle in R. is invariant under the group of rotations, then the scatterer is a circle. The theorem is generalized to the elastic scattering problems and the axisymmetric scatterers in R..
