The good-bad-ugly system near spatial infinity on flat spacetime
Miguel Duarte, Justin Feng, Edgar Gasperin +1
A system of equations that serves as a model for the Einstein field equation in generalised harmonic gauge called the good-bad-ugly system is studied in the region close to null an…
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…
Peeling in Generalized Harmonic Gauge
Miguel Duarte, Justin C. Feng, Edgar Gasperin +1
It is shown that a large class of systems of non-linear wave equations, based on the good-bad-ugly model, admit formal solutions with polyhomogeneous expansions near null infinity.…
