In this work we obtained solutions of field equations for perfect fluid spherically symmetric static spacetimes and found their concircular vector fields (CCVFs) in $f(R,T)$ gravity theory. It came out that special classes of these spacetimes possess either $4$-dimensional or $15$-dimensional CCVFs.

Concircular Vectors Field in (kappa; mu)-Contact Metric Manifolds
2017The aim of the present paper is to study (kappa,mu)-contact manifolds admitting a non-null concircularvector field and concurrent vector field. We prove that in both the cases the manifold becomes aSasakian manifold under certain restriction on kappa, mu.
