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.…
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…
ADDENDUM on the mass neutrino oscillation in a gravitational field
J. G. Pereira, C. M. Zhang
In the article {\it Gen. Rel. Grav.} {\bf 32}, 1633 (2000), by J. G. Pereira and C. M. Zhang, the special relativity energy-momentum tensor was used to discuss the neutrino phase-s…
Gravitation and the Local Symmetry Group of Spacetime
M. Calcada, J. G. Pereira
According to general relativity, the interaction of a matter field with gravitation requires the simultaneous introduction of a tetrad field, which is a field related to translatio…
