A Class of Quasi-Stationary Regular Line Elements for the Schwarzschild Geometry
arXiv:gr-qc/9407005
Abstract
A one-fold infinity of explicit quasi-stationary regular line elements for the Schwarzschild geometry is obtained directly from the vacuum Einstein equations. The class includes the familiar Eddington-Finkelstein coordinates, and the coordinates discussed recently by Kraus and Wilczek.
