| contents | Selected topics in teleparallel gravity R. Aldrovandi J. G. Pereira K. H. Vu Física, Astronomía y Matemáticas Teleparallel gravity can be seen as a gauge theory for the translation group. As such, its fundamental field isneither the tetrad nor the metric, but a gauge potential assuming values in the Lie algebra of the translationgroup. This gauge character makes of teleparallel gravity, despite its equivalence to general relativity, a ratherpeculiar theory. A first important point is that it does not rely on the universality of free fall, and consequentlydoes not require the equivalence principle to describe the gravitational interaction. Another peculiarity is itssimilarity with Maxwells theory, which allows an Abelian nonintegrable phase factor approach, and consequentlya global formulation for gravitation. Application of these concepts to the motion of spinless particles,as well as to the COW and gravitational Aharonov-Bohm effects are presented and discussed. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434714 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4A Vol.34 |
