Abstract

Over the past decade, f (R) theories have been extensively studied as one of the simplest modifications to General Relativity.In this article we review various applications of f (R) theories to cosmology and gravity -such as inflation, dark energy, local gravity constraints, cosmological perturbations, and spherically symmetric solutions in weak and strong gravitational backgrounds.We present a number of ways to distinguish those theories from General Relativity observationally and experimentally.We also discuss the extension to other modified gravity theories such as Brans-Dicke theory and Gauss-Bonnet gravity, and address models that can satisfy both cosmological and local gravity constraints.
