Proper Curvature Collineations of Plane Symmetric Static Spacetime in F(R) Theory of Gravity

SINDH UNIVERSITY RESEARCH JOURNAL -SCIENCE SERIES, 2018
The purpose of this paper is to study the proper curvature collineations of plane symmetric static spacetime in f(R) theory of gravity. We have taken the metrics of both constant and non-constant curvature and formulated the curvature vector fields by using vanishing Lie derivative and direct integration technique. Here, the solutions of the Einstein’s

A note on proper curvature collineations of vacuum classes of plane fronted gravitational waves in f(R) theory of gravity

International Journal of Geometric Methods in Modern Physics
Proper curvature collineations (CCs) of plane-fronted gravitational waves (GWs) in [Formula: see text] gravity are addressed in this paper. We first think about vacuum classes of plane GWs and analyze their CCs using mathematical and integration methods, and we also use a [Formula: see text] Riemann curvature matrix.
