A new satellite-based experiment in the field of gravitation, SaToR-G, is presented. It aims to compare predictions different theories gravitation limit weak-field and slow-motion. The ultimate goal SaToR-G searching for possible “new physics” beyond General Relativity, which represent state-of-the-art our current knowledge gravitational physics. key role above perspective theoretical experimen...

A discussion of the number of degrees of freedom, and their dynamical properties, in higher derivative gravitational theories is presented. The complete non-linear sigma model for these degrees of freedom is exhibited using the method of auxiliary fields. As a by-product we present a consistent non-linear coupling of a spin-2 tensor to gravitation. It is shown that non-vanishing (Cμναβ) 2 terms...

On the basis of a “local” principle of equivalence of general relativity, we consider a navigation in a kind of “4D-ocean” involving measurements of conformally invariant physical properties only. Then, applying the Pfaff theory for PDE to a particular conformally equivariant system of differential equations, we show the dependency of any kind of function describing “spacetime waves”, with resp...

The main scope of this paper is first of all to verify the efficiency of the flame atomic absorption spectroscopy (FAAS) method for analysis of some trace elements in extracts of fractionation analysis of the gravitation dust sediments. Investigation was oriented to the analysis of some markedly toxic trace elements in the extracts of gravitation dust sediments as well as on efficiency evaluati...

In this paper, a simple but efficient method of overlapping community detection is presented using local community gravitation in social networks. Given a highquality, non-overlapping partition generated by existing methods, this proposed method identifies the overlapping nodes from their surrounding partitioned communities according to their local community gravitation, with low computational ...

In this paper, I determine the electrogravitational field produced by a charged mass point according to the Relativistic Theory of Gravitation. The Causality Principle in the Relativistic Theory of Gravitation will play a very important part in finding this field. The analytical form and the domain of definition, i.e the gravitational radius of the obtained solution, differ from that given by E...

We study influence of gravitational field on the mass-energy equivalence relation by incorporating gravitation in the physical situation considered by Einstein (Ann. Physik, 17, 1905, English translation in ref. [1]) for his first derivation of mass-energy equivalence. In doing so, we also refine Einstein’s expression (Ann. Physik, 35, 1911, English translation in ref. [3]) for increase in grav...

Gravitation governs the expansion and fate of the universe, and the growth of large-scale structure within it, but has not been tested in detail on these cosmic scales. The observed acceleration of the expansion may provide signs of gravitational laws beyond general relativity (GR). Since the form of any such extension is not clear, from either theory or data, we adopt a model-independent appro...

The possibility of a symmetry between gravitating and anti-gravitating particles is examined. The properties of the anti-gravitating fields are defined by their behavior under general diffeomorphisms. The equations of motion and the conserved canonical currents are derived, and it is shown that the kinetic energy remains positive whereas the new fields can make a negative contribution to the so...

1. Fermion fields of the Standard Model. Fermion fields of the Standard Model are subdivided into two parts: lepton fields and quark fields. Lepton fields are subdivided into three generations. The first generation is represented by an electron e and an electronic neutrino νe, the second generation is represented by a muon μ and its neutrino νμ, and the third generation is represented by a tauo...
