Abstract

f(R) gravity is an extension of Einstein's General Relativity derived from relaxing the hypothesis that the Hilbert-Einstein action for the gravitational field is strictly linear in the Ricci curvature scalar R, i.e. f(R)=R. In this sense, f(R) gravity represents a class of theories defined as arbitrary functions of R. It can be considered as the simplest example of Extended Theory of Gravity (Capozziello and De Laurentis, 2011)
