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…
The Maxwell-scalar field system near spatial infinity
Marica Minucci, Rodrigo Panosso Macedo, Juan Antonio Valiente Kroon
We make use of Friedrich's representation of spatial infinity to study asymptotic expansions of the Maxwell-scalar field system near spatial infinity. The main objective of this an…
Evolution equations for a wide range of Einstein-matter systems
Mikael Normann, Juan Valiente Kroon
We use an orthonormal frame approach to provide a general framework for the first order hyperbolic reduction of the Einstein equations coupled to a fairly generic class of matter m…
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…
A characterisation of Schwarzschildean initial data
J. A. Valiente Kroon
A theorem providing a characterisation of Schwarzschildean initial data sets on slices with an asymptotically Euclidean end is proved. This characterisation is based on the proport…
Early radiative properties of the developments of time symmetric, conformally flat initial data
J. A. Valiente Kroon
Using a representation of spatial infinity based in the properties of conformal geodesics, the first terms of an expansion for the Bondi mass for the development of time symmetric,…
