Gravitation: in search of the missing torsion
R. Aldrovandi, J. G. Pereira
A linear Lorentz connection has always two fundamental derived characteristics: curvature and torsion. The latter is assumed to vanish in general relativity. Three gravitational mo…
Lorentz transformations in de Sitter relativity
R. Aldrovandi, J. P. Beltran Almeida, C. S. O. Mayor +1
The properties of Lorentz transformations in de Sitter relativity are studied. It is shown that, in addition to leaving invariant the velocity of light, they also leave invariant t…
The Nonlinear Essence of Gravitational Waves
R. Aldrovandi, J. G. Pereira, K. H. Vu
A critical review of gravitational wave theory is made. It is pointed out that the usual linear approach to the gravitational wave theory is neither conceptually consistent nor mat…
General Relativity as a Genuine Connection Theory
R. Aldrovandi, H. I. Arcos, J. G. Pereira
The Palatini formulation is used to develop a genuine connection theory for general relativity, in which the gravitational field is represented by a Lorentz-valued spin connection.…
Spin and Anholonomy in General Relativity
R. Aldrovandi, P. B. Barros, J. G. Pereira
In the general case, torsion couples to the spin current of the Dirac field. In General Relativity, the apparent torsion field to which the spin current of the Dirac field couples…
The Equivalence Principle Revisited
R. Aldrovandi, P. B. Barros, J. G. Pereira
A precise formulation of the strong Equivalence Principle is essential to the understanding of the relationship between gravitation and quantum mechanics. The relevant aspects are…
