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.…
Wu-Yang ambiguity in connection space
R. Aldrovandi, A. L. Barbosa
Two distinct gauge potentials can have the same field strength, in which case they are said to be ``copies'' of each other. The consequences of this possibility for the general spa…
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…
Spacetime algebraic skeleton
R. Aldrovandi, A. L. Barbosa
The cosmological constant Lambda, which has seemingly dominated the primaeval Universe evolution and to which recent data attribute a significant present-time value, is shown to ha…
On the pre-nucleosynthesis cosmological period
R. Aldrovandi, J. Gariel, G. Marcilhacy
Physics, as known from our local, around--earth experience, meets some of its applicability limits at the time just preceding the period of primeval nucleosynthesis. Attention is f…
