Foil 26 6: The Inner Boundary (cont.)

From Overview of BBH Simulations Physics Colloquium -- Oct 29 1998. by Scott Klasky
The Schwarzschild (Ingoing Eddington-Finklestein) and Kerr spacetimes use the Kerr-Schild form of the metric:
  • The metric is form invariant under a boost.
  • The 3+1 decomposition are unique for boosted Schwarzschild or Kerr.
  • 3+1 decomposition gives us initial data (gij, Kij) and coordinate conditions (a,bi) which we can then use.
  • The analytical apparent horizon location is known everywhere.
