A note on proper affine symmetry in Kantowski-Sachs and Bianchi type III space-times
Ghulam Shabbir, Nisar Ahmed
We investigate proper affine symmetry for the Kantowski-Sachs and Bianchi type III space-times by using holonomy and decomposability, the rank of the 6X6 Riemann matrix and direct…

Proper Affine Vector Fields in Plane Symmetric Static Space-Times
Ghulam Shabbir, Nisar Ahmed
A study of proper affine vector fields in plane symmetric static space-times by using the rank of the Rieman matrix and holonomy. Studying proper affine vector fields in each case,…
