Research

Invited lectures on our research at international conferences, workshops and seminars

Our international cooperation due to common projects and/or common research interests

Our research activity is mainly focussed on the numerical analysis, computational methods and applications of nonlinear partial differential equations, including

* free boundary problems - evolution of curves and surfaces governed by curvature, anisotropy and external forces, solved by
* Level-set methods
* Langrangean methods
* Phase-field approaches

* image processing

* image smoothing by anisotropic and geometry driven diffusion
* image segmentation by curvature driven flows
* 3D image sequence processing

* flow in porous media and simulations of groundwater flows

* physical geodesy - determination of Earth geoid by the boundary element method

* numerical methods for derivative securities pricing in financial mathematics
