Hyperbolic Equations for Vacuum Gravity Using Special Orthonormal Frames
arXiv:gr-qc/9703072 · doi:10.1088/0264-9381/14/5/025
Abstract
By adopting Nester's higher dimensional special orthonormal frames (HSOF) the tetrad equations for vacuum gravity are put into first order symmetric hyperbolic (FOSH) form with constant coefficients, independent of any time slicing or coordinate specialization.
