POINTLESS SPACES IN GENERAL RELATIVITY [PDF]

open access: yes, 1995
The new approach to quantize the gravity based on the notion of differential algebra is suggested. It is shown that the differential geometry of this object can not be described in terms of points.

Cylindrical systems in general relativity [PDF]

open access: yesClassical and quantum gravity, 2019
With the arrival of the era of gravitational wave astronomy, the strong gravitational field regime will be explored soon in various aspects. In this article, we provide a general review over cylindrical systems in Einstein’s theory of general relativity.

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

Anisotropic Stars in General Relativity [PDF]

open access: yes, 2001
We present a class of exact solutions of Einstein's gravitational field equations describing spherically symmetric and static anisotropic stellar type configurations. The solutions are obtained by assuming a particular form of the anisotropy factor.

General relativity from causality

open access: yesJournal of High Energy Physics, 2017
We study large families of theories of interacting spin 2 particles from the point of view of causality. Although it is often stated that there is a unique Lorentz invariant effective theory of massless spin 2, namely general relativity, other theories ...

Dipolar Particles in General Relativity [PDF]

open access: yes, 2006
The dynamics of "dipolar particles", i.e. particles endowed with a four-vector mass dipole moment, is investigated using an action principle in general relativity. The action is a specific functional of the particle's world line, and of the dipole moment

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. The main historical confirmations of General Relativity will be described.

General relativity and cosmology [PDF]

open access: yesInternational Journal of Modern Physics D, 2015
This year marks the 100th anniversary of Einstein’s 1915 landmark paper “Die Feldgleichungen der Gravitation” in which the field equations of general relativity were correctly formulated for the first time, thus rendering general relativity a complete theory.

Hierarchical Test of General Relativity with Gravitational Waves. [PDF]

open access: yesPhysical Review Letters, 2019
We propose a hierarchical approach to testing general relativity with multiple gravitational wave detections. Unlike existing strategies, our method does not assume that parameters quantifying deviations from general relativity are either common or ...

General Relativity and Experiment [PDF]

open access: yes, 1999
The confrontation between Einstein's theory of gravitation and experiment is summarized. Although all current experimental data are compatible with general relativity, the importance of pursuing the quest for possible deviations from Einstein's theory is emphasized.
