DESCRIPTION:Given the sharp logarithmic decay of linear waves on the Kerr-
 AdS black hole (Holzegel\, Smulevici '13)\, it is expected that the Kerr-A
 dS spacetime is unstable as a solution of the Einstein vacuum equations. H
 owever\, the scattering construction presented here for exponentially deca
 ying nonlinear waves on a fixed Kerr-AdS background serves as a first step
  to confronting the scattering problem for the full Einstein system. In th
 is context\, one may hope to derive a class of perturbations of Kerr-AdS w
 hich remain 'close' and dissipate sufficiently fast.
