Are non-Kerr spacetimes integrable? — •Georgios Lukes-Gerakopoulos — Theoretical Physics Institute, Friedrich-Schiller-Universität Jena, D-07743 Jena, Germany

The only known axisymmetric and stationary vacuum solution of the Einstein equation which corresponds to integrable system is the Kerr spacetime. However, in the last few years there were attempts to find Carter-like constants in non-Kerr spacetimes, i.e. in spacetimes that are axisymmetric and stationary perturbations of the Kerr spacetime. In this talk we are going to discuss whether the Carter constant is unique or not and the implications of this issue.
