The Momentum Constraints of General Relativity and Spatial Conformal Isometries
R. Beig, N. Ó Murchadha
Transverse-tracefree (TT-) tensors on , with an asymptotically flat metric of fast decay at infinity, are studied. When the source tensor from which th…
The Constraints in Spherically Symmetric General Relativity II --- Identifying the Configuration Space: A Moment of Time Symmetry
Jemal Guven, Niall Ó Murchadha
We continue our investigation of the configuration space of general relativity begun in I (gr-qc/9411009). Here we examine the Hamiltonian constraint when the spatial geometry is m…
The Constraints in Spherically Symmetric General Relativity I --- Optical Scalars, Foliations, Bounds on the Configuration Space Variables and the Positivity of the Quasi-Local Mass
Jemal Guven, Niall Ó Murchadha
We examine the constraints of spherically symmetric general relativity with one asymptotically flat region, exploiting both the traditional metric variables and variables construct…
Trapped surfaces and the Penrose inequality in spherically symmetric geometries
Edward Malec, Niall Ó Murchadha
We demonstrate that the Penrose inequality is valid for spherically symmetric geometries even when the horizon is immersed in matter. The matter field need not be at rest. The only…
