Research Interests
My research interests are in application of differential geometrical methods to general relativity, classical field theories and classical mechanics. I have worked on Lagrangian formulations of classical field theories, in particular, Einstein's general relativity and the transition to the Newtonian Limit. Similarly I have investigated the relation between Hamiltonian multiparticle systems in a symplectic formulation with relativistic, i.e. Poincaré invariant formulations.

Within Einstein's General Relativity Theory proper I investigated asymptotically Euclidean static and stationary perfect fluid models and made some contributions towards a proof that they must be spherically symmetric in the static case and have unique slightly ellipsoidal configurations for small angular velocity, the configuration depending only on the equation of state, the total mass and the angular momentum.

For the last about ten years I have concentrated on classical solutions of the Einstein-Yang-Mills field equations. Einstein's gravitation theory and the Yang-Mills gauge theories describe the most fundamental forces of physics. Both theories will have to be quantized for the most precise description of nature, but also investigating the classical field equations is most interesting.

I am now looking at finding analytical and numerical solutions for systems with a very high symmetry, like static ones with spherical symmetry and cosmological solutions with homogeneous space-like sections. Such models are also particularly interesting mathematically because there is no natural action of the symmetry group on the principal bundle on which the Yang-Mills connections are given, but rather there are many possible actions which can be classified like Lie group representations.
