| Decay of fields in general relativity |
| Speaker: | Jérémie Joudioux (University of Vienna) |
| Abstract: | One of the main problem studied these days in the field of mathematical general relativity is a proof of the stability of the slowly rotating black holes, known as Kerr black holes. The understanding of this stability mostly relies on establishing good decay/scattering properties of higher spin fields (such as Maxwell fields) evolving on the Kerr background. After a short presentation on the meaning of the stability of the Einstein equation in the context of the Cauchy problem, the decay properties of the most simple toy model, the scalar wave equation (spin-0 field) on the flat background, will be described and the obstructions to the generalization of these scattering properties of solutions of the scalar wave on black holes will be explained. Finally, a reduction process of higher spin fields to the scalar wave equation, introduced by Penrose, will be given. |

| Pulsars and Extreme Physics |
| Speaker: | Prof. Dr. Jocelyn Bell Burnell |
| Abstract: | Pulsars were discovered some 40 years ago. What do we know about them now
and what have they taught us about the extremes of physics? With an
average density comparable to that of the nucleus, magnetic fields of
around 100 000 000 T and speeds close to c, they have stretched our
understanding of the behavior of matter. They serve as extremely accurate
clocks with which to carry out precision experiments in relativity. Pulsar
research continues to deliver exciting, startling and almost unbelievable
results.
