Perturbations of Dark Matter Gravity
M. D. Maia, A. J. S. Capistrano, D. Muller
Until recently the study of the gravitational field of dark matter was primarily concerned with its local effects on the motion of stars in galaxies and galaxy clusters. On the oth…
On the Nature of the Cosmological Constant Problem
M. D. Maia, A. J. S. Capistrano, E. M. Monte
General relativity postulates the Minkowski space-time to be the standard flat geometry against which we compare all curved space-times and the gravitational ground state where par…
Pound-Rebka experiment and torsion in the Schwarzschild spacetime
J. W. Maluf, S. C. Ulhoa, F. F. Faria
We develop some ideas discussed by E. Schucking [arXiv:0803.4128] concerning the geometry of the gravitational field. First, we address the concept according to which the gravitati…
Galilean Covariance and the Gravitational Field
S. C. Ulhoa, F. C. Khanna, A. E. Santana
The paper is concerned with the development of a gravitational field theory having locally a covariant version of the Galilei group. We show that this Galilean gravity can be used…
