我们考虑了修正的$f(R)$引力，它可以统一$R^m$早期暴胀和晚期$ λ $CDM epoch。结果表明，该模型通过了局部检验（牛顿定律、类地引力解的稳定性、附加标量自由度的非常重的质量），并提出了广义相对论的现实替代方案。讨论了$f(R)$ $\Lambda$CDM时代未来发展的各种场景。
We consider modified $f(R)$ gravity which may unify $R^m$ early-time inflation with late-time $\Lambda$CDM epoch. It is shown that such model passes the local tests (Newton law, stability of Earth-like gravitational solution, very heavy mass for additional scalar degree of freedom) and suggests the realistic alternative for General Relativity. Various scenarios for future evolution of $f(R)$ $\Lambda$CDM era are discussed.
