- W4206571501 abstract "The main object of this paper is to investigate spacetimes admitting concircular curvature tensor in f ( R ) gravity theory. At first, concircularly flat and concircularly flat perfect fluid spacetimes in <mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML id=m1><mml:mi>f</mml:mi><mml:mfenced open=( close=)><mml:mrow><mml:mi>R</mml:mi></mml:mrow></mml:mfenced></mml:math> gravity are studied. In this case, the forms of the isotropic pressure p and the energy density σ are obtained. Next, some energy conditions are considered. Finally, perfect fluid spacetimes with divergence free concircular curvature tensor in f ( R ) gravity are studied; amongst many results, it is proved that if the energy-momentum tensor of such spacetimes is recurrent or bi-recurrent, then the Ricci tensor is semi-symmetric and hence these spacetimes either represent inflation or their isotropic pressure and energy density are constants." @default.
