f(R) is a type of modified gravity theory which generalizes Einstein's general relativity. f(R) gravity is actually a family of theories, each one defined by a different function, f, of the Ricci scalar, R. The simplest case is just the function being equal to the scalar; this is general relativity. As a consequence of … See more Derivation of field equations In metric f(R) gravity, one arrives at the field equations by varying the action with respect to the metric and not treating the connection The variation of the … See more As there are many potential forms of f(R) gravity, it is difficult to find generic tests.
