Numerical initial data deformation exploiting a gluing construction: I. Exterior asymptotic Schwarzschild
Boris Daszuta, Jörg Frauendiener
In this work a new numerical technique to prepare Cauchy data for the initial value problem (IVP) formulation of Einstein's field equations is presented. Directly inspired by the e…

A spectral method for half-integer spin fields based on spin-weighted spherical harmonics
Florian Beyer, Boris Daszuta, Joerg Frauendiener
We present a new spectral scheme for analysing functions of half-integer spin-weight on the -sphere and demonstrate the stability and convergence properties of our implementatio…
