Proper curvature symmetry in non-static cylindrically symmetric Lorentzian manifolds
Ghulam Shabbir, M. Ramzan
We considered the most general form of non-static cylindrically symmetric space-times for studying proper curvature symmetry by using the rank of the 6X6 Riemann matrix and direct…

Classification of non conformally flat cylindrically symmetric non static space-times according to their proper conformal motions
Ghulam Shabbir, M. Ramzan, Suhail Khan
In this paper we considered the most general form of non conformally flat cylindrically symmetric non-static space-times to study proper conformal motions using direct integration…

Classification of Kantowski-Sachs and Bianchi Type III space-times according to their proper conformal vector fields
Ghulam Shabbir, Suhail Khan, M. Ramzan
We investigate proper conformal vector fields in non conformally flat Kantowski-Sachs and Bianchi type III space-times using direct integration technique. Using the above mentioned…
