Thermal equilibrium in general relativity and the special nature of the cosmological constant
M. L. Rodrigues, J. B. Formiga
The problem of thermal equilibrium in general relativity is discussed and the unique role played by the fluid associated with the cosmological constant is emphasized. In addition t…
Angular momentum in the teleparallel equivalent of general relativity
J. B. Formiga, R. D. Costa
In teleparallelism one is able to tackle the gravitational energy and angular momentum problems in a way that distinguishes this theory from other theories of gravity, such as gene…
Gravitational energy in pp-wave spacetimes
R. D. Costa, J. B. Formiga
The description of the gravitation energy is a long standing problem. Although some success has been achieved, there is no satisfactory solution to this problem yet. Probably the m…
On the gravitational energy problem and the energy of photons
J. B. Formiga, João Duarte
The lack of a well-established solution for the gravitational energy problem might be one of the reasons why a clear road to quantum gravity does not exist. In this paper, the grav…
The generalization of the ADM gravitational energy-momentum
J. B. Formiga, V. R. Gonçalves
In this paper, it is proved that the teleparallel energy-momentum generalizes that of the ADM formalism. In doing so, it is shown that the teleparallel -momentum can be made to…
The meaning of torsion in teleparallel theories
J. B. Formiga
The ambiguity of the Weitzenböck connection and the meaning of torsion in teleparallel theories are investigated. A new postulate is added to teleparallel theories in order to remo…
