Electrodynamic Radiation Reaction and General Relativity
Carlos Kozameh, Ezra T. Newman, Raul Ortega +1
We argue that the well-known problem of the instabilities associated with the self-forces (radiation reaction forces) in classical electrodynamics are possibly stabilized by the in…
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…
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…
The Universal Cut Function and Type II Metrics
C. Kozameh, E. T. Newman, J. G. Santiago-Santiago +1
In analogy with classical electromagnetic theory, where one determines the total charge and both electric and magnetic multipole moments of a source from certain surface integrals…
On the Physical Meaning of the Robinson-Trautman-Maxwell Fields
Carlos Kozameh, E. T. Newman, Gilberto Silva-Ortigoza
We study the Robinson-Trautman-Maxwell Fields in two closely related coordinate systems, the original Robinson-Trautman (RT) coordinates (in a more general context, often referred…
Twisting Null Geodesic Congruences and the Einstein-Maxwell Equations
Ezra T. Newman, Gilberto Silva-Ortigoza
The purpose of the present work is to extend the earlier results for asymptotically flat vacuum space-times to asymptotically flat solutions of the Einstein-Maxwell equations. Once…
Tensorial Spin-s Harmonics
Ezra T. Newman, Gilberto Silva-Ortigoza
We show how to define and go from the spin-s spherical harmonics to the tensorial spin-s harmonics. These quantities, which are functions on the sphere taking values as Euclidean t…
Twisting Null Geodesic Congruences, Scri, H-Space and Spin-Angular Momentum
Carlos. Kozameh, E. T. Newman, Gilberto Silva-Ortigoza
The purpose of this work is to return, with a new observation and rather unconventional point of view, to the study of asymptotically flat solutions of Einstein equations. The esse…
N-dimensional geometries and Einstein equations from systems of PDE's
Emanuel Gallo, Magdalena Marciano-Melchor, Gilberto Silva-Ortigoza
The aim of the present work is twofold: first, we show how all the -dimensional Riemannian and Lorentzian metrics can be constructed from a certain class of systems of second-or…
