Charged Dilaton, Energy, Momentum and Angular-Momentum in Teleparallel Theory Equivalent to General Relativity
Gamal Gergess Lamee Nashed
We apply the energy-momentum tensor to calculate energy, momentum and angular-momentum of two different tetrad fields. This tensor is coordinate independent of the gravitational fi…
Møller's energy of the Kerr-NUT Metric
Gamal G. L. Nashed
The energy distribution of the Kerr-NUT space-time is calculated using Møller's energy-momentum complex within the framework of the Riemannian geometry.
Energy and angular momentum of general 4-dimensional stationary axi-symmetric spacetime in teleparallel geometry
Gamal Gergess Lamee Nashed
We derive an exact general axi-symmetric solution of the coupled gravitational and electromagnetic fields in the tetrad theory of gravitation. The solution is characterized by four…
Comments Brane-World Black Holes and Energy-Momentum Vector
Gamal Gergess Lamee Nashed
We show that the energy distribution of the brane-world black holes given by Salti et al. in the context of teleparallel theory is not right. We give the correct formula of energy…
Charged Axially Symmetric Solution and Energy in Teleparallel Theory Equivalent to General Relativity
Gamal Gergess Lamee Nashed
An exact charged solution with axial symmetry is obtained in the teleparallel equivalent of general relativity (TEGR). The associated metric has the structure function $G(ξ)=1-ξ^2-…
Reissner-Nordström Spacetime in the Tetrad Theory of Gravitation
Gamal G. L. Nashed, Takeshi Shirafuji
We give two classes of spherically symmetric exact solutions of the couple gravitational and electromagnetic fields with charged source in the tetrad theory of gravitation. The fir…
