Spherically Symmetric Geometries in f(T) and f(R) Gravitational Theories
Using the well know relation between Ricci scalar, R, and torsion scalar, T, that is, R=-T-2∇αTα, we show that, for any spherically symmetric spacetime whose (i) scalar torsion vanishing, that is, T=TμναSαμν=0 or (ii) total derivative term, that is, ∇αTα with Tα is the contraction of the torsion, va...
