Kivonat:
We generalize the result of Lukacs  et al. on asymptotic stability of the
Schwarzschild metric with respect to perturbations in the Robinson-Trautman
class of metrics to the case of Petrov type II twisting metrics, under the
condition of asymptotic flatness at future null infinity. The Bondi energy
is used as the Lyapunov functional and we prove that the "final state" of
such metrics is the Kerr metric.
