在过去的十年中，f（R）理论作为广义相对论最简单的修正之一被广泛研究。在这篇文章中，我们回顾了各种应用的f（R）理论的宇宙学和引力-如通货膨胀，暗能量，局部引力约束，宇宙学扰动，球对称的解决方案，在弱和强引力背景。我们提出了多种方法来从观察和实验上区分这些理论与广义相对论。我们还讨论了扩展到其他修改的引力理论，如Brans-Dicke理论和Gauss-Bonnet引力，并解决模型，可以同时满足宇宙学和局部引力约束。
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.
