Charged Rotating BTZ Black Hole and Thermodynamic Behavior of Field Equations at its Horizon
M. Akbar, Azad A. Siddiqui
In this paper, we study different cases of the charged rotating BTZ black hole with reference to their horizons. For the existence of these cases conditions on mass, charge and ang…
Asymptotic Behaviour of the Proper Length and Volume of the Schwarzschild Singularity
Asghar Qadir, Azad A. Siddiqui
Though popular presentations give the Schwarzschild singularity as a point it is known that it is spacelike and not timelike. Thus it has a "length" and is not a "point". In fact,…
Uniqueness of Flat Spherically Symmetric Spacelike Hypersurfaces Admitted by Spherically Symmetric Static Spactimes
Robert Beig, Azad A. Siddiqui
It is known that spherically symmetric static spacetimes admit a foliation by °at hypersurfaces. Such foliations have explicitly been constructed for some spacetimes, using differe…
K-Slicing the Reissner-Nordstrom Spacetime: Some New Observations
Asghar Qadir, M. Sajid, Azad A. Siddiqui
There were problems encountered in extending the K-slicing of the Schwarzschild and Reissner-Nordstrom (RN) spacetimes [1, 2] to the extreme case, when charge equals mass (in gravi…
Foliation of the Kottler-Schwarzschild-De Sitter Spacetime by Flat Spacelike Hypersurfaces
Azad A. Siddiqui
There exist Kruskal like coordinates for the Reissner-Nordstrom (RN) black hole spacetime which are regular at coordinate singularities. Non existence of such coordinates for the e…
