Energy of a Regular Black Hole
M. Sharif
We use Einstein, Landau-Lifshitz, Papapetrou and Weinberg energy-momentum complexes to evaluate energy distribution of a regular black hole. It is shown that for a regular black ho…
Classification of Static Plane Symmetric Spacetimes according to their Matter Collineations
M. Sharif
In this paper we classify static plane symmetric spacetimes according to their matter collineations. These have been studied for both cases when the energy-momentum tensor is non-d…
Energy and Momentum in Spacetime Homogeneous Gdel-type Metrics
M. Sharif
Using Einstein and Papapetrou energy-momentum complexes, we explicitly calculate the energy and momentum distribution associated with spacetime homogeneous Gdel-type metr…
Matter collineations of Spacetime Homogeneous Gödel-type Metrics
U. Camci, M. Sharif
The spacetime homogeneous Gödel-type spacetimes which have four classes of metrics are studied according to their matter collineations. The obtained results are compared with Killi…
Classification of Spherically Symmetric Static Spacetimes according to their Matter Collineations
M. Sharif, Sehar Aziz
The spherically symmetric static spacetimes are classified according to their matter collineations. These are studied when the energy-momentum tensor is degenerate and also when it…
