Conformal geodesics on vacuum space-times

چکیده
We discuss properties of conformal geodesics on general, vacuum, and warped product space-times and derive a system of conformal deviation equations. The results are used to show how to construct on the Schwarzschild-Kruskal space-time global conformal Gauss coordinates which extends smoothly and without degeneracy to future and past null infinity.

On solutions of the vacuum Einstein equation in the radiation regime
We review recent results by the author, in collaboration with Erwann Delay, Olivier Lengard, and Rafe Mazzeo, on existence and properties of space-times with controlled asymptotic behavior at null infinity. The standard description of gravitational radiation proceeds as follows: one considers space-times (M , g) which can be conformally completed by adding a boundary ∂M = I , so that an appropr...
متن کاملThe principle of equivalence and projective structure in space - times
This paper discusses the extent to which one can determine the space-time metric from a knowledge of a certain subset of the (unparametrised) geodesics of its Levi-Civita connection, that is, from the experimental evidence of the equivalence principle. It is shown that, if the space-time concerned is known to be vacuum, then the Levi-Civita connection is uniquely determined and its associated m...
متن کاملOn de Sitter-like and Minkowski-like space-times
Friedrich’s proofs for the global existence results of de Sitter-like space-times and of semiglobal existence of Minkowski-like space-times [Comm. Math. Phys. 107, 587 (1986)] are re-examined and discussed, making use of the extended conformal field equations and a gauge based on conformal geodesics. In this gauge the location of the conformal boundary of the space-times is known a priori once ...
متن کاملA study of the spherically symmetric vacuum solution to Conformal (Weyl) Gravity
We study in detail the static spherically symmetric vacuum solution to conformal (Weyl) gravity. One of the more striking aspects of the solution is the presence of a physical singularity at r = 0 due to the linear term in the metric. Using Penrose diagrams we determine which conformally flat space-times allow light to scatter from infinity and calculate the trajectories and deflection of light...
متن کاملConformal boundary extensions of Lorentzian manifolds
We study the question of local and global uniqueness of completions, based on null geodesics, of Lorentzian manifolds. We show local uniqueness of such boundary extensions. We give a necessary and sufficient condition for existence of unique maximal completions. The condition is verified in several situations of interest. This leads to existence and uniqueness of maximal spacelike conformal bou...
