Torsion as Alternative to Curvature in the Description of Gravitation
V. C. de Andrade, H. I. Arcos, J. G. Pereira
The general covariance principle, seen as an active version of the principle of equivalence, is used to study the gravitational coupling prescription in the presence of curvature a…
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.…
Torsion and the Gravitational Interaction
H. I. Arcos, J. G. Pereira
By using a nonholonomous-frame formulation of the general covariance principle, seen as an active version of the strong equivalence principle, an analysis of the gravitational coup…
Lessons of spin and torsion: Reply to ``Consistent coupling to Dirac fields in teleparallelism"
Yu. N. Obukhov, J. G. Pereira
In reply to the criticism made by Mielke in the pereceding Comment [Phys. Rev. D69 (2004) 128501] on our recent paper, we once again explicitly demonstrate the inconsistency of the…
Cosmological Term and Fundamental Physics
R. Aldrovandi, J. P. Beltran Almeida, J. G. Pereira
A nonvanishing cosmological term in Einstein's equations implies a nonvanishing spacetime curvature even in absence of any kind of matter. It would, in consequence, affect many of…
Torsion and Gravitation: A new view
H. I. Arcos, V. C. de Andrade, J. G. Pereira
According to the teleparallel equivalent of general relativity, curvature and torsion are two equivalent ways of describing the same gravitational field. Despite equivalent, howeve…
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…
