Einstein Equations in the Null Quasi - spherical Gauge
Properties of the Einstein equations in a coordinate gauge based on expanding null hypersurfaces foliated by metric 2-spheres are described. This null quasi-spherical (NQS) gauge leads to particularly simple analyses of the characteristic structure of the equations and of the propagation of gravitational shocks, and clarifies the geometry of timelike boundary condition. A feature of the NQS gau...
متن کاملEinstein equations in the null quasi-spherical gauge III: numerical algorithms
We describe numerical techniques used in our construction of a 4th order in time evolution for the full Einstein equations, and assess the accuracy of some representative solutions. The scheme employs several novel geometric and numerical techniques, including a geometrically invariant coordinate gauge, which leads to a characteristic-transport formulation of the underlying hyperbolic system, c...
متن کاملSpectral collocation methods for solution of Einstein's equations in null quasi-spherical coordinates
The spectral methods which are being used to solve Einstein's equations in null quasi-spherical coordinates are described. They include Fast Fourier methods for evaluating derivatives in a uniform grid representation and methods for transforming to and from spin-weighted spherical harmonic representations. In theory, expressions involving spherical harmonics up to any xed maximum angular moment...
