    The Assumption of Spatially Localized Magnetizations and its Effect on some Inverse Problems in Geomagnetism

    Many problems in geoscience suffer from non-uniqueness issues. A particular example is the reconstruction of magnetizations from knowledge of the corresponding magnetic field. In this talk, we give an overview on recent results in that direction and the consequences for some related problems. Such related problems are the separation of geomagnetic fields into a crustal and a core contribution and the reconstruction of inducing dipole directions from knowledge of the induced magnetic field. We focus on the assumption that the underlying magnetizations are spatially localized and illustrate that this can improve on the intrinsic non-uniqueness of the problems.
