A nearly cylindrically symmetric source in the Brans-Dicke gravity as the generator of the rotational curves of the galaxies
S. Mittmann dos Santos, J. M. Hoff da Silva, M. E. X. Guimarães +1
Observation shows that the velocities of stars grow by approximately 2 to 3 orders of magnitude when the distances from the centers of the galaxies are in the range of kpc to…
Straight spinning cosmic strings in Brans-Dicke gravity
S. Mittmann dos Santos, J. M. Hoff da Silva, J. L. Cindra
It is presented an exact solution of straight spinning cosmic strings in Brans-Dicke theory of gravitation. The possibility of the existence of closed timelike curves around these…
Weyl frames and canonical transformations in geometrical scalar-tensor theories of gravity
A. B. Barreto, M. L. Pucheu, C. Romero
We consider scalar-tensor theories of gravity defined in Weyl integrable space-time and show that in the ADM formalism Weyl transformations corresponding to change of frames induce…
