Limit to General Relativity in f(R) theories of gravity
Gonzalo J. Olmo
We discuss two aspects of f(R) theories of gravity in metric formalism. We first study the reasons to introduce a scalar-tensor representation for these theories and the behavior o…

Violation of the Equivalence Principle in Modified Theories of Gravity
Gonzalo J. Olmo
We study modified theories of gravity of the f(R) type in Palatini formalism. For a generic f(R) lagrangian, we show that the metric can be solved as the product of a scalar functi…
