Spherically symmetric and static solutions in $f (R)$ gravity coupled with EM fields

Roger A. Hurtado, Jose R. Arenas

Solutions of field equations in $f (R)$ gravity are found for a spherically symmetric and static spacetime in the Born-Infeld (BI) non-linear electrodynamics. It is found that the m…

Scalar-field potential for viable models in $f (R)$ theory

Roger A. Hurtado, Robel Arenas

The $f (R)$ theory of gravity can be expressed as a scalar tensor theory with a scalar degree of freedom $ϕ$ . By a conformal transformation, the action and its Gibbons-York-Hawking…
