Dark matter effects of a black hole with nonsingular Yukawa-modified potential in Einstein-Gauss-Bonnet Gravity
Yassine Sekhmani, A. A. Araújo Filho, Ratbay Myrzakulov +3
This paper investigates the contribution of the nonsingular Yukawa-modified potential in the context of four-dimensional Einstein-Gauss-Bonnet (EGB) gravity modeling by a static an…
De Sitter-invariant approach to cosmology
A. V. Araujo, D. F. López, J. G. Pereira +1
The spacetime short-distance structure at the Planck scale is governed by the Planck length, usually interpreted as a three-dimensional Euclidian length. As such, it is not Lorentz…
de Sitter invariant special relativity and galaxy rotation curves
A. Araujo, D. F. Lopez, J. G. Pereira
Owing to the existence of an invariant length at the Planck scale, Einstein special relativity breaks down at that scale. A possible solution to this problem is arguably to replace…
de Sitter-invariant special relativity and the dark energy problem
A. Araujo, D. F. Lopez, J. G. Pereira
The replacement of the Poincaré-invariant Einstein special relativity by a de Sitter-invariant special relativity produces concomitant changes in all relativistic theories, includi…
Entropy in locally-de Sitter spacetimes
A. Araujo, J. G. Pereira
As quotient spaces, Minkowski and de Sitter are fundamental spacetimes in the sense that they are known "a priori", independently of Einstein equation. They represent different non…
On the spacetime connecting two aeons in conformal cyclic cosmology
A. Araujo, H. Jennen, J. G. Pereira +2
As quotient spaces, Minkowski and de Sitter are fundamental, non-gravitational spacetimes for the construction of physical theories. When general relativity is constructed on a de…
