Self-dual Lorentzian Wormholes and Energy in Teleparallel Theory of Gravity
Gamal Gergess Lamee Nashed
Two spherically symmetric, static Lorentzian wormholes are obtained in tetrad theory of gravitation as a solution of the equation , where $ρ=T_{ij}u^iu^j, ρ_t=(T_{ij}-{1/2…
Effect of Spin-Torsion Interaction on Raychaudhuri Equation
M. I. Wanas, M. A. Bakry
Raychaudhuri equation is generalized in the parameterized absolute parallelism geometry. This version of absolute parallelism is more general than the conventional one. The general…
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…
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-…
