Conserved currents in gravitational models with quasi-invariant Lagrangians: Application to teleparallel gravity
Yuri N. Obukhov, Guillermo F. Rubilar, J. G. Pereira
Conservation laws in gravitational theories with diffeomorphism and local Lorentz symmetry are studied. Main attention is paid to the construction of conserved currents and charges…
de Sitter special relativity
R. Aldrovandi, J. P. Beltran Almeida, J. G. Pereira
A special relativity based on the de Sitter group is introduced, which is the theory that might hold up in the presence of a non-vanishing cosmological constant. Like ordinary spec…
Bringing Together Gravity and the Quanta
R. Aldrovandi, L. C. T. Guillen, J. G. Pereira +1
Due to its underlying gauge structure, teleparallel gravity achieves a separation between inertial and gravitational effects. It can, in consequence, describe the isolated gravitat…
Holographic Dark Energy and the Universe Expansion Acceleration
J. P. Beltran Almeida, J. G. Pereira
By incorporating the holographic principle in a time-depending Lambda-term cosmology, new physical bounds on the arbitrary parameters of the model can be obtained. Considering then…
