The Hyperboloidal Numerical Evolution of a Good-Bad-Ugly Wave Equation
Edgar Gasperin, Shalabh Gautam, David Hilditch +1
One method for the numerical treatment of future null-infinity is to decouple coordinates from the tensor basis and choose each in a careful manner. This dual-frame approach is ham…

The Weak Null Condition in Free-evolution Schemes for Numerical Relativity: Dual Foliation GHG with Constraint Damping
Edgar Gasperin, David Hilditch
All strategies for the treatment of future null-infinity in numerical relativity involve some form of regularization of the field equations. In a recent proposal that relies on the…

Polyhomogeneous expansions from time symmetric initial data
Edgar Gasperin, Juan A. Valiente Kroon
We make use of Friedrich's construction of the cylinder at spatial infinity to relate the logarithmic terms appearing in asymptotic expansions of components of the Weyl tensor to t…
