Homothetic Vectors of Bianchi Type I Spacetimes in Lyra Geometry and General Relativity
Ahmad T Ali, Suhail Khan, Azeb Alghanemi
In this paper Bianchi type I spacetimes are completely classified by their homothetic vectors in the context of Lyra geometry. The non-linear coupled Lyra homothetic equations are…

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…
