Research Interests:
The research interests of the group lie in the area of Geometric and Quantitative Complex Analysis using in particular many methods of real analysis. This is an area in which geometry, analysis, topology and algebra come to work together creating a rich set of phenomena which still have to be understood. Applications of the results of the research in this area can be found in many other directions of Pure Mathematics (like in Algebraic Geometry, Number Theory, Topology etc.), but also in recent Theoretical Physics and in the area of Scientific Computing.

Major topics of research are:
  • Geometry of real, in particular pseudoconvex hypersurfaces
  • Solution of the Cauchy-Riemann equations with estimates
  • Extension of holomorphic functions
  • Pluripotential theory and its Greene functions
  • Quantitative aspects of the Bergman theory
  • Regularity of holomorphic and of CR maps with applications
  • The Levi problem for complex spaces with singularities
The research group is since a long time part of a european research network in Complex Analysis and Analytic Geometry comprising other groups in universities in
  • Bonn, Berlin, Pisa, Florence, Rome, Grenoble, Paris 6, Göteborg, Stockholm
Furthermore, there are permanent active research relations to groups at
  • Lille (France)
  • University of Michigan, Ann Arbor (USA)
  • Indiana University, Bloomington (USA)
