Editorial note to: André Lichnerowicz, Propagators, commutators and anti-commutators in general relativity

relativity yet existed, received new input from relativistic physics, the theory of distributions, and the tools of modern analysis and algebra. Some milestones were, in chronological order, the Hadamard ... concepts studied in the Lichnerowicz lectures, i.e. the quantum theory of Klein–Gordon and Dirac fields with the associated propagators, and the physical applications of Clifford’s algebra, but the

Cosmologies with Scalar Fields from Higher Dimensions Applied to Bianchi Type Model: Classical and Quantum Solutions

We construct an effective four-dimensional model by compactifying a ten-dimensional theory of gravity coupled with a real scalar dilaton field on a time-dependent torus. The corresponding action in ... higher-dimensional theory of gravity, and our analysis covers the classical and quantum aspects. In the frame of classical analysis we obtained that two radii of the Bianchi type are proportional, and we

Superdensity operators for spacetime quantum mechanics

Abstract We introduce superdensity operators as a tool for analyzing quantum information in spacetime. Superdensity operators encode spacetime correlation functions in an operator framework, and ... .

Gravitational Physics: the birth of a new era

General theory of Relativity. Notwithstanding, General Relativity is not adequate to explain the earliest stages of cosmic existence, and cannot provide an explanation for the Big Bang itself. Modern early ... rigorous underpinning in Quantum Gravity. - Gfor the large-scale dynamics of the cosmos — the eneral Relativity, the well-known Albert Einstein’s theory, describes warps in space-time, and accounts

An Optical Scalar Approach to Weak Gravitation Lensing

We assume a thick gravitational lens governed by a Baltz n=1 matter density model. From the gravitational potential we then derive expressions for a Weyl tensor component and Ricci tensor component ... an axially symmetric lens and source. I. Introduction The pre-relativity idea of gravitation was that objects with mass would interact with each other directly. The strength of this gravitational

Einstein and Rastall theories of gravitation in comparison

Visser’s ones. We indeed argue that these two theories are not equivalent. In fact, Rastall theory of gravity is an “open” theory when compared to Einstein general theory of relativity. Thus, it is ready to ... [ 8,9 ]. A key point is that all of the potential alternatives to Einstein’s general theory of relativity (GTR) must be viable. This implies that alternative theories must be in agreement with the

Stratified scalar field theories of gravitation with self-energy term and effective particle Lagrangian

We construct a general stratified scalar theory of gravitation from a field equation that accounts for the self-interaction of the field and a particle Lagrangian, and calculate its post-Newtonian ... parameters from some parameters of the field equation and of particle Lagrangian would be of great help. General relativity, so far the most successful theory, is a tensorial theory of gravitation. But, it is
