A generalized Principle of Relativity [PDF]
Chaos, 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.

Curvature Dynamics in General Relativity
Universe, 2023 The equations of general relativity are recast in the form of a wave equation for the Weyl tensor. This allows reformulation of gravitational wave theory in terms of curvature waves, rather than metric waves.

The 3+1 formalism in teleparallel and symmetric teleparallel gravity
European 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

GENERALIZED SPACES OF GENERAL RELATIVITY [PDF]
Proceedings 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 ...

Galaxies, 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.

Conformally Coupled General Relativity
Universe, 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

General relativity from causality
Journal 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 ...
