ON THE UNIQUENESS AND GLOBAL DYNAMICS OF ADS SPACETIMES MICHAEL T. ANDERSON
 

Summary: ON THE UNIQUENESS AND GLOBAL DYNAMICS OF ADS SPACETIMES
MICHAEL T. ANDERSON
Abstract. We study global aspects of complete, non-singular asymptotically locally AdS space-
times solving the vacuum Einstein equations whose conformal infinity is an arbitrary globally sta-
tionary spacetime. It is proved that any such solution which is asymptotically stationary to the
past and future is itself globally stationary.
This gives certain rigidity or uniqueness results for exact AdS and related spacetimes.
1. Introduction
Consider geodesically complete, asymptotically simple solutions of the vacuum Einstein equations
with negative cosmological constant < 0 in (n+1) dimensions. Up to rescaling, these are given by
complete, (non-singular), metrics g, defined on manifolds of the form Mn+1 = R, and satisfying
the Einstein equations
(1.1) Ricg = -ng.
The metric g has a conformal completion, at least C2, with conformal boundary (I, []), where
is a complete Lorentz metric on I. Topologically, conformal infinity I is of the form R .
The canonical example is the (exact) anti-de Sitter spacetime gAdS, which may be represented
globally in static form as
(1.2) gAdS = - cosh2
r dt2
+ dr2
