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.

f (R)的理论

在过去的十年里，f(R)理论作为广义相对论最简单的修正之一得到了广泛的研究。在这篇文章中，我们回顾了f(R)理论在宇宙学和引力中的各种应用，例如暴胀、暗能量、局部引力约束、宇宙摄动以及弱和强引力背景下的球对称解。我们提出了一些从观测和实验上区分这些理论与广义相对论的方法。我们还讨论了其他修正的引力理论，如Brans-Dicke理论和Gauss-Bonnet引力的推广，以及可以同时满足宇宙学和局部引力约束的模型。

期刊介绍： Living Reviews in Relativity is a peer-reviewed, platinum open-access journal that publishes reviews of research across all areas of relativity. Directed towards the scientific community at or above the graduate-student level, articles are solicited from leading authorities and provide critical assessments of current research. They offer annotated insights into key literature and describe available resources, maintaining an up-to-date suite of high-quality reviews, thus embodying the "living" aspect of the journal's title. Serving as a valuable tool for the scientific community, Living Reviews in Relativity is often the first stop for researchers seeking information on current work in relativity. Written by experts, the reviews cite, explain, and assess the most relevant resources in a given field, evaluating existing work and suggesting areas for further research. Attracting readers from the entire relativity community, the journal is useful for graduate students conducting literature surveys, researchers seeking the latest results in unfamiliar fields, and lecturers in need of information and visual materials for presentations at all levels.
