Implications of Kleinian relativity

F. A. P. Alves, A. B. Barreto, F. Moraes

Inspired in metamaterials, we present a covariant mechanics for particles in Kleinian spacetime and show some of its effects, such as time contraction and length dilatation. We pre…

Cosmological Solutions for the Geometrical Scalar-Tensor with the Potential Determined by the Noether Symmetry Approach

Adriano B. Barreto, Gilberto M. Kremer

In this work we consider a scale-tensor theory in which the space-time is endowed with a Weyl integrable geometrical structure due to the Palatini variational method. Since the sca…

From quasinormal modes of rotating black strings to hydrodynamics of a moving CFT plasma

Luis A. H. Mamani, Jaqueline Morgan, Alex S. Miranda +1

A certain identification of points in a planar Schwarzschild-anti de Sitter (AdS) black hole generates a four-dimensional static black string. In turn, a rotating black string can…

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…

Separable wave equations for gravitoelectromagnetic perturbations of rotating charged black strings

Alex S. Miranda, Jaqueline Morgan, Vilson T. Zanchin +1

Rotating charged black strings are solutions of four-dimensional Einstein-Maxwell equations with a negative cosmological constant and a non-trivial topology. According to the AdS/C…
