Trapped surfaces in spherical expanding open universes
Uwe Brauer, Edward Malec, Niall Ó Murchadha
Consider spherically symmetric initial data for a cosmology which, in the large, approximates an open Friedmann-Lema{\^ı}tre universe. Further assume that the data i…
Weakly decaying asymptotically flat static and stationary solutions to the Einstein equations
Daniel Kennefick, Niall Ó Murchadha
The assumption that a solution to the Einstein equations is static (or stationary) very strongly constrains the asymptotic behaviour of the metric. It is shown that one need only i…
Trapped Surfaces in Vacuum Spacetimes
R. Beig, N. Ó Murchadha
An earlier construction by the authors of sequences of globally regular, asymptotically flat initial data for the Einstein vacuum equations containing trapped surfaces for large va…
Brill Waves
Niall Ó Murchadha
Brill waves are the simplest (non-trivial) solutions to the vacuum constraints of general relativity. They are also rich enough in structure to allow us believe that they capture,…
