A generalized Principle of Relativity [PDF]

open access: yesChaos, Solitons & Fractals, 2009
In this paper we bring to light an hitherto undisclosed richness of this Theory, namely its admitting a consistent reformulation which is able to provide a unified scenario for all kinds of particles, be they lightlike or not. This result hinges on a "generalized" Principle of Relativity which is {intrinsic} to Einstein's Theory.

Self-force and radiation reaction in general relativity [PDF]

open access: yesReports on progress in physics. Physical Society, 2018
The detection of gravitational waves from binary black-hole mergers by the LIGO–Virgo Collaboration marks the dawn of an era when general-relativistic dynamics in its most extreme manifestation is directly accessible to observation.

GENERALIZED SPACES OF GENERAL RELATIVITY [PDF]

open access: yesProceedings of the National Academy of Sciences, 1959
1. This paper is a revision of the paper with the same title which was published a year ago. The paper deals with a space of four dimensions V4 of coordinates xi as i takes the values 1 to 4. The geometry of the space is based upon the asymmetric functions gij and the asymmetric coefficients of connection Prk and upon the Einsteinm equation2 gij,k ...

The 3+1 formalism in teleparallel and symmetric teleparallel gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Teleparallel and symmetric teleparallel gravity offer platforms in which gravity can be formulated in interesting geometric approaches, respectively given by torsion and nonmetricity. In this vein, general relativity can be expressed in three dynamically

Tests of General Relativity with GW170817. [PDF]

open access: yesPhysical Review Letters, 2018
The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new type of source.

Formal statement of the special principle of relativity [PDF]

open access: yes, 2013
While there is a longstanding discussion about the interpretation of the extended, general principle of relativity, there seems to be a consensus that the special principle of relativity is absolutely clear and unproblematic.

Nonlocal General Relativity

open access: yesGalaxies, 2014
A brief account of the present status of the recent nonlocal generalization of Einstein’s theory of gravitation is presented. The main physical assumptions that underlie this theory are described.

General Relativity from Scattering Amplitudes. [PDF]

open access: yesPhysical Review Letters, 2018
Weoutline the program to apply modern quantum field theory methods to calculate observables in classical general relativity through a truncation to classical terms of the multigraviton, two-body, on-shell scattering amplitudes between massive fields ...

Testing general relativity with present and future astrophysical observations [PDF]

open access: yes, 2015
One century after its formulation, Einstein's general relativity (GR) has made remarkable predictions and turned out to be compatible with all experimental tests.
