- Title
Coordinates problem of Hawking radiation derivation in a KerrâNewman black hole using HamiltonâJacobi equation.
- Authors

- Abstract
Hawking radiation from a Kerr-Newman black hole is investigated using Hamilton-Jacobi method more deeply. A direct computation will lead to a wrong result via Hamilton-Jacobi method. However, when the well-behaved Painleve coordinate system and Eddington coordinate system are considered, we can get the correct result. The reason of the discrepancy between naive coordinate and well-behaved coordinates is also discussed.
