Abstract: Inverse scattering and impedance tomography have been very active fields of applied mathematics in recent years. In particular for shape reconstruction problems new trends have emerged allowing to obtain new insights and encouraging results for well established and fascinating inverse problems. Examples include the development of qualitative reconstruction algorithms, such as linear sampling, factorization and monotonicity methods, techniques to deal with limited sets of data like backscattering data, limited aperture data or single wave measurements, algorithms that are particularly adapted to special scatterer geometries, and methods that use multi-frequency information or time-dependent measurements, to name just a few. The minisymposium focuses on recent developments and innovative contributions in this direction.
