On Extracting Physical Content from Asymptotically Flat Space-Time Metrics
C. Kozameh, E. T. Newman, G. Silva-Ortigoza
A major issue in general relativity, from its earliest days to the present, is how to extract physical information from any solution or class of solutions to the Einstein equations…
On the well posedness of Robinson Trautman Maxwell solutions
Carlos Kozameh, Oscar Reula, Heinz-Otto Kreiss
We show that the so called Robinson-Trautman-Maxwell equations do not constitute a well posed initial value problem. That is, the dependence of the solution on the initial data is…
The Geometry of Regular Shear-Free Null Geodesic Congruences, CR functions and their Application to the Flat-Space Maxwell Equations
Carlos Kozameh, E. T. Newman, Gilberto Silva-Ortigoza
We describe here what appears to be a new structure that is hidden in all asymptotically vanishing Maxwell fields possessing a non-vanishing total charge. Though we are dealing wit…
Light Propagation on Quantum Curved Spacetime and Back reaction effects
Carlos Kozameh, Florencia Parisi
We study the electromagnetic field equations on an arbitrary quantum curved background in the semiclassical approximation of Loop Quantum Gravity. The effective interaction hamilto…
Asymptotically Shear-free and Twist-free Null Geodesic Congruences
Carlos Kozameh, Ezra T. Newman
We show that, though they are rare, there are asymptotically flat space-times that possess null geodesic congruences that are both asymptotically shear- free and twist-free (surfac…
Superselection Sectors in Asymptotic Quantization of Gravity
Alfredo E. Dominguez, Carlos N. Kozameh, Malcolm Ludvigsen
Using the continuity of the scalar (the mass aspect) at null infinity through we show that the space of radiative solutions of general relativity can be thought of a fi…
