J un 2 00 5 Radiative spacetimes approaching the Vaidya metric
We analyze a class of exact type II solutions of the Robinson–Trautman family which contain pure radiation and (possibly) a cosmological constant. It is shown that these spacetimes exist for any sufficiently smooth initial data, and that they approach the spherically symmetric Vaidya–(anti-)de Sitter metric. We also investigate extensions of the metric, and we demonstrate that their order of sm...
متن کاملHow Inflationary Spacetimes Might Evolve into Spacetimes of Finite Total Mass
We consider how the finite mass shock wave cosmology introduced by the authors in [6] could connect up with Guth’s original theory of inflation.
متن کاملSpacetimes admitting quasi-conformal curvature tensor
The object of the present paper is to study spacetimes admitting quasi-conformal curvature tensor. At first we prove that a quasi-conformally flat spacetime is Einstein and hence it is of constant curvature and the energy momentum tensor of such a spacetime satisfying Einstein's field equation with cosmological constant is covariant constant. Next, we prove that if the perfect flui...
متن کاملAsymptotic symmetries of Schrödinger spacetimes
We discuss the asymptotic symmetry algebra of the Schrödinger-invariant metrics in d + 3 dimensions and its realization on finite temperature solutions of gravity coupled to matter fields. These solutions have been proposed as gravity backgrounds dual to non-relativistic CFTs with critical exponent z in d space dimensions. It is known that the Schrödinger algebra possesses an infinite-dimension...
متن کاملAsymptotically Plane Wave Spacetimes and their Actions
We propose a definition of asymptotically plane wave spacetimes in vacuum gravity in terms of the asymptotic falloff of the metric, and discuss the relation to previously constructed exact solutions. We construct a well-behaved action principle for such spacetimes, using the formalism developed by Mann and Marolf. We show that this action is finite on-shell and that the variational principle is...
