Conformal vector fields in proper non-static plane symmetric spacetimes in f(R) gravity
Abstract
Nonstatic plane symmetric spacetimes are considered to study conformal vector fields (VFs) in the f(R) theory of gravity. Firstly, we investigate some proper nonstatic plane symmetric spacetimes by solving the Einstein field equations (EFEs) in the f(R) theory of gravity using algebraic techniques. Secondly, we find CVFs of the obtained spacetimes by means of the direct integration approach. There exist seven cases. Studying each case in detail, we find that the CVFs are of dimension three, five, six and fifteen.
