报告摘要:

The asymptotically anti-de Sitter spacetime with a hypersurfaceorthogonal Killing vector field is discussed near infinity by usingNewman-Penrose formalism.   We first investigate the multipolestructure of a static, asymptotically anti-de Sitter spacetime. We note that,different to asymptotically flat case in which the multipoles arecontained in  $\Psi_0^k$, the multipoles of a static, asymptoticallyanti-de Sitter spacetime are all contained in $\Psi_2^0$. We then show that whenthe spherical harmonic expansion of $\Psi_2^0$ is finite,  theSchwarzschild anti-de Sitter spacetime is the only asymptotically anti-de Sitter,static, axisymmetric, type-D solution of vacuum Einstein equation with a negativecosmological constant in a Bondi coordinate neighborhood of null infinity. Inaddition, the uniqueness of Schwarzschild de Sitter spacetime near nullinfinity has also been discussed.
