Hyperboloidal evolution with the Einstein equations
Anil Zenginoglu
We consider an approach to the hyperboloidal evolution problem based on the Einstein equations written for a rescaled metric. It is shown that a conformal scale factor can be freel…
A hyperboloidal study of tail decay rates for scalar and Yang-Mills fields
Anıl Zenginoğlu
We investigate the asymptotic behavior of spherically symmetric solutions to scalar wave and Yang-Mills equations on a Schwarzschild background. The studies demonstrate the astroph…
Hyperboloidal foliations and scri-fixing
Anıl Zenginoğlu
We discuss a gauge choice which allows us to avoid the introduction of artificial timelike outer boundaries in numerical studies of test fields based on a 3+1 decomposition of asym…
Hyperboloidal foliations with scri-fixing in spherical symmetry
Anil Zenginoglu, Sascha Husa
We study in spherical symmetry the conformal compactification for hyperboloidal foliations with nonvanishing constant mean curvature. The conformal factor and the coordinates are c…
Numerical calculations near spatial infinity
Anil Zenginoglu
After describing in short some problems and methods regarding the smoothness of null infinity for isolated systems, I present numerical calculations in which both spatial and null…
