Conformal Collineations of the Ricci and Energy-Momentum Tensors in Static Plane Symmetric Spacetimes
Sumaira Saleem Akhtar, Tahir Hussain, Ashfaque Hussain Bokhari +1
Considering the degenerate and non-degenerate cases, we provide a complete classification of static plane symmetric spacetimes according to conformal Ricci collineations (CRCs) and…
Classification of LRS Bianchi type I Spacetimes via Conformal Ricci Collineations
Tahir Hussain, Sumaira Saleem Akhtar, Fawad Khan
In this paper, we present a complete classification of Locally Rotationally Symmetric (LRS) Bianchi type I spacetimes according to their Conformal Ricci Collineations (CRCs). When…
Conformal Killing Vectors Of Plane Symmetric Four Dimensional Lorentzian Manifolds
Suhail Khan, Tahir Hussain, Ashfaque H. Bokhari +9
In this paper, we investigate conformal Killing's vectors (CKVs) admitted by some plane symmetric spacetimes. Ten conformal Killing's equations and their general forms of CKVs are…
Noether Symmetries of Bianchi Type II Spacetime Metrics
Mahmood Rajih Tarayrah, Hassan Azad, Ashfaque H. Bokhari +1
We classify a class of Bianchi type II spacetimes according to their Noether symmetries. We briefly discuss the conservation laws admitted by these Noether symmetries and classify…
Generalization of the double reduction theory
Ashfaque H. Bokhari, Ahmad Y. Dweik, F. D. Zaman +2
In a recent work [1, 2] Sjoberg remarked that generalization of the double reduction theory to partial differential equations of higher dimensions is still an open problem. In this…
Weighing the Milky Way
Munawar Karim, Angelo Tartaglia, Ashfaque H. Bokhari
We describe an experiment to measure the mass of the Milky Way galaxy. The experiment is based on calculated light travel times along orthogonal directions in the Schwarzschild met…
