Asymptotics of spin-0 fields and conserved charges on n-dimensional Minkowski spaces
Edgar Gasperín, Mariem Magdy, Filipe C. Mena
We use conformal geometry methods and the construction of Friedrich's cylinder at spatial infinity to study the propagation of spin- fields (solutions to the wave equation) on $…
Regularizing Dual-Frame Generalized Harmonic Gauge at Null Infinity
Miguel Duarte, Edgar Gasperín, Justin C. Feng +1
The dual-frame formalism leads to an approach to extend numerical relativity simulations in generalized harmonic gauge (GHG) all the way to null infinity. A major setback is that w…
Almost-Killing equation: Stability, hyperbolicity, and black hole Gauss law
Justin C. Feng, Edgar Gasperín, Jarrod L. Williams
We examine the Hamiltonian formulation and hyperbolicity of the almost-Killing equation (AKE). We find that for all but one parameter choice, the Hamiltonian is unbounded, and in s…
