On Uniqueness of Kerr Space-time near null infinity

الأصل · EN

We re-express the Kerr metric in standard Bondi-Saches' coordinate near null infinity I+. Using the uniqueness result of characteristic initial value problem, we prove the Kerr metric is the only asymptotic flat, stationary, axial symmetric, Type-D solution of vacuum Einstein equation. The Taylor series of Kerr space-time is expressed in terms of B-S coordinates and the N-P constants have been calculated.
