Abstract

We consider modified f(R) gravity which may unify R^m early-time inflation with late-time \ensuremathΛCDM epoch. It is shown that such a 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 the future evolution of f(R) \ensuremathΛCDM era are discussed.
