Local Decay of Waves on Asymptotically Flat Stationary Space-times
In this article we study the pointwise decay properties of solutions to the wave equation on a class of stationary asymptotically flat backgrounds in three space dimensions. Under the assumption that uniform energy bounds and a weak form of local energy decay hold forward in time we establish a t−3 local uniform decay rate for linear waves. This work was motivated by open problems concerning de...
متن کاملVan Stockum – Bonnor Class of Asymptotically Flat Space-times
We find an infinite sequence of axially symmetric multipole solutions of Einstein equations in space-time of rigidly moving dust along field lines of time translation Killing vector. The resulting line element is necessarily of the van-Stockum class. The corresponding space-times are smooth, apart from the centre, stationary, asymptotically flat, and, for radii sufficiently large, cylindrically...
متن کامل5 The Large Footprints of H - Space on Asymptotically Flat Space - Times Carlos
We show that certain structures defined on the complex four dimensional space known as H-Space have considerable relevance for its closely associated asymptotically flat real physical space-time. More specifically for every complex analytic curve on the H-space there is an asymptotically shear-free null geodesic congruence in the physical space-time. There are specific geometric structures that...
متن کاملThe Isometry Groups of Asymptotically Flat, Asymptotically Empty Space–Times with Timelike ADM Four–Momentum
We give a complete classification of all connected isometry groups, together with their actions in the asymptotic region, in asymptotically flat, asymptotically vacuum space–times with timelike ADM four–momentum.
متن کاملNatural flat observer fields in spherically-symmetric space-times
An observer field in a space-time is a time-like unit vector field. It is natural if the integral curves (field lines) are geodesic and the perpendicular 3–plane field is integrable (giving normal space slices). It then follows that the field determines a coherent notion of time: a time coordinate that is constant on the perpendicular space slices and whose difference between two space slices i...
