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 energy transported by exact plane gravitational-wave solutions
Yuri N. Obukhov, J. G. Pereira, Guillermo F. Rubilar
The energy and momentum transported by exact plane gravitational-wave solutions of Einstein equations are computed using the teleparallel equivalent formulation of Einstein's theor…
Regularizing role of teleparallelism
Tiago Gribl Lucas, Yuri N. Obukhov, J. G. Pereira
The properties of the gravitational energy-momentum 3-form and of the superpotential 2-form are discussed in the covariant teleparallel framework, where the Weitzenböck connection…
Gravitation as Anholonomy
R. Aldrovandi, P. B. Barros, J. G. Pereira
A gravitational field can be seen as the anholonomy of the tetrad fields. This is more explicit in the teleparallel approach, in which the gravitational field-strength is the torsi…
Metric-affine approach to teleparallel gravity
Yu. N. Obukhov, J. G. Pereira
The teleparallel gravity theory, treated physically as a gauge theory of translations, naturally represents a particular case of the most general gauge-theoretic model based on the…
Teleparallel origin of the Fierz picture for spin-2 particle
Yu. N. Obukhov, J. G. Pereira
A new approach to the description of spin-2 particle in flat and curved spacetime is developed on the basis of the teleparallel gravity theory. We show that such an approach is in…
