The Einstein-Friedrich-nonlinear scalar field system and the stability of scalar field Cosmologies
Artur Alho, Filipe C. Mena, Juan A. Valiente Kroon
A frame representation is used to derive a first order quasi-linear symmetric hyperbolic system for a scalar field minimally coupled to gravity. This procedure is inspired by simil…
On the construction of a geometric invariant measuring the deviation from Kerr data
Thomas Bäckdahl, Juan A. Valiente Kroon
This article contains a detailed and rigorous proof of the construction of a geometric invariant for initial data sets for the Einstein vacuum field equations. This geometric invar…
Geometric Invariant Measuring the Deviation from Kerr Data
Thomas Bäckdahl, Juan A. Valiente Kroon
A geometrical invariant for regular asymptotically Euclidean data for the vacuum Einstein field equations is constructed. This invariant vanishes if and only if the data correspond…
