Wellposedness of the initial boundary value problem for the conformal field equations
Chris Stevens, Juan A. Valiente Kroon
We provide a formulation of the initial boundary value problem for Friedrich's extended conformal Einstein field equations in which boundary data is prescribed on a timelike hypers…

Controlled regularity at future null infinity from past asymptotic initial data: the wave equation
Jordan Marajh, Grigalius Taujanskas, Juan A. Valiente Kroon
We study the relationship between asymptotic characteristic initial data for the wave equation at past null infinity and the regularity of the solution at future null infinity on t…
