Nonlocal General Relativity [PDF]

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.

Testing general relativity in cosmology [PDF]

open access: yesLiving Reviews in Relativity, 2018
We review recent developments and results in testing general relativity (GR) at cosmological scales. The subject has witnessed rapid growth during the last two decades with the aim of addressing the question of cosmic acceleration and the dark energy ...

Tests of General Relativity with GW150914. [PDF]

open access: yesPhysical Review Letters, 2016
The LIGO detection of GW150914 provides an unprecedented opportunity to study the two-body motion of a compact-object binary in the large-velocity, highly nonlinear regime, and to witness the final merger of the binary and the excitation of uniquely ...

Landauer Principle and General Relativity [PDF]

open access: yesEntropy, 2020
We endeavour to illustrate the physical relevance of the Landauer principle applying it to different important issues concerning the theory of gravitation.

Carroll Expansion of General Relativity [PDF]

open access: yesSciPost Physics, 2022
We study the small speed of light expansion of general relativity, utilizing the modern perspective on non-Lorentzian geometry. This is an expansion around the ultra-local Carroll limit, in which light cones close up. To this end, we first rewrite the

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.

Noncommutative General Relativity [PDF]

open access: yesPhysical Review D, 2005
We define a theory of noncommutative general relativity for canonical noncommutative spaces. We find a subclass of general coordinate transformations acting on canonical noncommutative spacetimes to be volume-preserving transformations.

A logic road from special relativity to general relativity [PDF]

open access: yesSynthese Volume 186, Number 3 (2012), 633-649, 2010
We present a streamlined axiom system of special relativity in first-order logic. From this axiom system we "derive" an axiom system of general relativity in two natural steps. We will also see how the axioms of special relativity transform into those of general relativity.

Testing General Relativity [PDF]

open access: yesProceedings of Gran Sasso Summer Institute 2014 Hands-On Experimental Underground Physics at LNGS — PoS(GSSI14), 2015
This lecture will present a review of the past and present tests of the General Relativity theory. The essentials of the theory will be recalled and the measurable effects will be listed and analyzed.

Conformally Coupled General Relativity

open access: yesUniverse, 2018
The gravity model developed in the series of papers (Arbuzov et al. 2009; 2010), (Pervushin et al. 2012) is revisited. The model is based on the Ogievetsky theorem, which specifies the structure of the general coordinate transformation group. The theorem
