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.

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.

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.

A HERO for General Relativity [PDF]

open access: yesUniverse, 2019
HERO (Highly Eccentric Relativity Orbiter) is a space-based mission concept aimed to perform several tests of post-Newtonian gravity around the Earth with a preferably drag-free spacecraft moving along a highly elliptical path fixed in its plane ...

The Power of General Relativity [PDF]

open access: yesPhysical Review D, 2005
We study the cosmological and weak-field properties of theories of gravity derived by extending general relativity by means of a Lagrangian proportional to $R^{1+\delta}$. This scale-free extension reduces to general relativity when $\delta \to 0$.

What is General Relativity? [PDF]

open access: yesPhysica Scripta, 2017
General relativity is a set of physical and geometric principles, which lead to a set of (Einstein) field equations that determine the gravitational field, and to the geodesic equations that describe light propagation and the motion of particles on the ...

Coincident general relativity [PDF]

open access: yesPhysical Review D, 2017
The Palatini's device is applied to generate teleparallel and symmetric teleparallel theories of gravity. From the latter is discovered an exceptional class which is consistent with a vanishing affine connection.

Numerical Hydrodynamics in General Relativity [PDF]

open access: yesLiving Reviews in Relativity, 2000
The current status of numerical solutions for the equations of ideal general relativistic hydrodynamics is reviewed. Different formulations of the equations are presented, with special mention of conservative and hyperbolic formulations well-adapted to ...

Dynamic Aether as a Trigger for Spontaneous Spinorization in Early Universe

open access: yesUniverse, 2023
In the framework of the Einstein–Dirac-aether theory we consider a phenomenological model of the spontaneous growth of the fermion number, which is triggered by the dynamic aether.
