Gravitation and Duality Symmetry
V. C. de Andrade, A. L. Barbosa, J. G. Pereira
By generalizing the Hodge dual operator to the case of soldered bundles, and working in the context of the teleparallel equivalent of general relativity, an analysis of the duality…
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…
Teleparallel Equivalent of Non-Abelian Kaluza-Klein Theory
A. L. Barbosa, L. C. T. Guillen, J. G. Pereira
Based on the equivalence between a gauge theory for the translation group and general relativity, a teleparallel version of the non-abelian Kaluza-Klein theory is constructed. In t…
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…
Mass Generation from Lie Algebra Extensions
R. Aldrovandi, V. C. de Andrade, A. L. Barbosa +1
Applied to the electroweak interactions, the theory of Lie algebra extensions suggests a mechanism by which the boson masses are generated without resource to spontaneous symmetry…
Topics in Born-Infeld Electrodynamics
R. Kerner, A. L. Barbosa, D. V. Gal'tsov
Classical version of Born-Infeld electrodynamics is recalled and its most important properties discussed. Then we analyze possible abelian and non-abelian generalizations of this t…
