| 1 | Causal structure of Black holes such that no boundary conditions are required at and inside the apparent horizon of the black hole. |
| 2 | Require a good choice of "coordinates" in order to take advantage of this |
| 3 | The only problems that we have been able to do, have been "model problems" which give us coordinate conditions for static rotating, moving black holes (Choice corresponds to the Kerr-Schild spacetime metric or ingoing Eddington-Finkelstein coordinates for Schwarzschild black holes) |
