On the Consistence Conditions to Braneworlds Sum Rules in Scalar-Tensor Gravity for Arbitrary Dimensions
M. C. B. Abdalla, M. E. X. Guimaraes, J. M. Hoff da Silva
We derive an one-parameter family of consistence conditions to braneworlds in the Brans-Dicke gravity. The sum rules are constructed in a completely general frame and they reproduc…
Non- symmetric braneworlds in scalar tensorial gravity
M. C. B. Abdalla, M. E. X. Guimaraes, J. M. Hoff da Silva
We obtain, via the Gauss-Codazzi formalism, the expression of the effective Einstein-Brans-Dicke projected equations in a non- symmetric braneworld scenario which p…
Gauss-Codazzi Formalism to Braneworld Scenario within Brans-Dicke Theory
M. C. B. Abdalla, M. E. X. Guimaraes, J. M. Hoff da Silva
We apply the Gauss-Codacci formalism to brane worlds scenario within the framework of Brans-Dicke gravity. The compactification is taken from six to five dimensions in order to for…
Brane Cosmic String Compactification in Brans-Dicke Theory
M. C. B. Abdalla, M. E. X. Guimaraes, J. M. Hoff da Silva
We investigate an alternative compactification of extra dimensions using local cosmic string in the Brans-Dicke gravity framework. In the context of dynamical systems it is possibl…
Self-Interactions in the Spacetime of a Scalar-Tensor Cosmic String
I. V. L. Costa, F. A. Oliveira, M. E. X. Guimaraes +1
We study the effect of the geometry and topology of a scalar-tensor cosmic string space-time on the electric and magnetic fields of line sources. It is shown that the dilatonic cou…
Quantum Effects in the Spacetime of a Magnetic Flux Cosmic String
M. E. X. Guimaraes, A. L. N. Oliveira
In this work we compute the vacuum expectation values of the energy-momentum tensor and the average value of a massive, charged scalar field in the presence of a magnetic flux cosm…
