چکیده
A bstract We propose a definition of asymptotic flatness at timelike infinity in four spacetime dimensions. present detailed study the equations motion and action supertranslations on fields. show that Lee-Wald symplectic form Ω( g, δ 1 g , 2 ) does not get contributions from future with our boundary conditions. As result, “future charges” can be computed any two-dimensional surface surrounding sources infinity. expressions for supertranslation Lorentz charges.

Timelike Infinity and Asymptotic Symmetry
By extending Ashtekar and Romano’s definition of spacelike infinity to the timelike direction, a new definition of asymptotic flatness at timelike infinity for an isolated system with a source is proposed. The treatment provides unit spacelike 3-hyperboloid timelike infinity and avoids the introduction of the troublesome differentiability conditions which were necessary in the previous works on...
متن کاملFrom Now to Timelike Infinity on a Finite Grid
In the articles [1, 2, 3, 4] we presented a complete code for solving the conformal Einstein equations which will allow us to study many interesting questions about the global structure of spacetimes by performing numerical experiments. In the present paper we want to demonstrate some of the unique capabilities of this code by a simple example: We calculate the time evolution of gravitational w...
متن کاملSupertranslations to all orders
The transformation laws of the general linear superfield V (x, θ, θ) and chiral superfields under N = 1 supertranslations exp[i(ζ ·Q+Q · ζ)] are tabulated to all orders in the parameters ζ , ζ.
متن کاملSupertranslations and Superrotations at the Black Hole Horizon.
We show that the asymptotic symmetries close to nonextremal black hole horizons are generated by an extension of supertranslations. This group is generated by a semidirect sum of Virasoro and Abelian currents. The charges associated with the asymptotic Killing symmetries satisfy the same algebra. When considering the special case of a stationary black hole, the zero mode charges correspond to t...
متن کاملMaximum Principles at Infinity
We prove a general maximum principle at infinity for properly immersed minimal surfaces with boundary in R. An important corollary of this maximum principle at infinity is the existence of a fixed sized regular neighborhood for any properly embedded minimal surface of bounded curvature.
