Geomathematics Group
The Geomathematics Group at the Department 6 (Department of Mathematics) of the University of Siegen is concerned with the development and application of new mathematical techniques for problems in the geosciences - but not only there. Medical imaging is also an investigated field of application. Here are some of the current focusses of the research of the Geomaths Group:
- Modelling of the Earth's interior based on gravitational and seismic data: this involves the use of spaceborne gravity models (based on satellite missions) and the use of earthquake travel-times as well as spectral anomalies of the free oscillations of the Earth after major earthquakes.
- Mathematical seismology: we are interested in the improvement of mathematical models in seismology with respect to theory and numerics.
- Constructive approximation on the 3D-ball: Improved numerical methods are developed in order to calculate functions on the 3D-ball in an efficient way, i.e. both the approximation error and the calculation time have to be kept acceptably small.
- MEG/EEG: A joint research project with A.S. Fokas and O. Hauk (Cambridge) is concerned with the theory and numerics of the inverse problems with respect to magneto- and electroencephalography.
