The Relation Between Technique of Conformal Flat and Damour-Ruffini-Zhao's Method
arXiv:gr-qc/0010079
Abstract
The relation between the technique of conformal flat and Damour-Ruffini-Zhao's method is investigated in this paper. It is pointed out that the two methods give the same results when the metric has the form $g_{αβ=0},$ with $α=0,1$ and $β=2,3$. It is indicated that the two methods are not equivalent for general case.
