Kivonat:

    The Kerr spacetime is, arguably, one of the most important exact
solutions to the vacuum Einstein field equations. It describes a
rotating stationary black hole, and it is expected to describe, in some
sense, the final stage of the evolution of a dynamical black hole
spacetime. The Kerr spacetime is characterised by the existence of a
so-called Killing spinor with a very particular asymptotic behaviour at
infinity. In this talk I will discuss an ongoing research programme
(carried out in collaboration with T. Bäckdahl) to construct geometric
invariants which allow to establish in a precise and rigorous manner what
it means that a dynamical black hole is close to a member of the Kerr
family. The connection between these invariants and some fundamental
problems in the mathematical theory of black holes will be explored
during the talk.
