Gravitational waves and the breaking of parallelograms in space-time
J. W. Maluf, S. C. Ulhoa, J. F. da Rocha-Neto
We show that plane-fronted gravitational waves induce the breaking of parallelograms in space-time, in the context of the teleparallel equivalent of general relativity (TEGR). The…

Gravitational energy-momentum flow in binary systems
J. W. Maluf, S. C. Ulhoa, J. F. da Rocha-Neto
We investigate the gravitational energy-momentum distribution in the space-time of two black holes in circular orbit, in the context of the teleparallel equivalent of general relat…

Teleparallel formalism of galilean gravity
S. C. Ulhoa, F. C. Khanna, A. E. Santana
A pseudo-Riemannian manifold is introduced, with light-cone coordinates in (4+1) dimensional space-time, to describe a Galilei covariant gravity. The notion of 5-bein and torsion a…
