Spectral-infinite element method approach for computing asymptotically flat initial data sets in general relativity
Published 17 Jul 2023 in gr-qc | (2307.08867v2)
Abstract: In this work, we introduce a spectral-infinite element method for solving Einstein's constraint equations in hyperbolic form. As an application of this, we use this method for computing asymptotically flat perturbations of a Kerr black hole with small angular momentum. Our numerical infrastructure is based on the use of a spin-weighted spherical harmonic transform combined with an infinite element method for solving partial differential equations in unbounded domains.
