This picture arose from computer calculations using basic properties
of Lorentzian manifolds. It represents a black hole.

- Where do the Einstein equations come from? The Einstein equations as stationary points of a variational problem
- gravitational waves
- special solutions of Einstein's equations, e.g. the Kerr solution for rotating black holes
- sagemath/python tools to do calculations in general relativity
- the positive mass theorem
- wave equations on Lorentzian manifolds, leading to quatization of fields
- solving the Einstein equations as a pde
- more about causality, Cauchy hypersurfaces, global hyperbolicity This lecture will be held in the summer term 2021. It will be held via the video software zoom. The access data for the zoom conference are available on the GRIPS system after you have registered there for the lecture.
- The Yamabe problem

Monday 8.15-10.00 in M102 and Wednesday 8-15-10.00 in M101
