"Unified f(R) models of inflation and dark energy"

f(R) gravity is a simple and nontrivial extension of General Relativity which has recently received much attention to explain the accelerating expansion of the Universe without cosmological constant. We construct viable f(R) models for both cosmic accelerating expansion in the early and late time Universe. The models should satisfy the certain viable conditions for not only positive Ricci scalar but also negative Ricci scalar, which is realized at the end of the R2 inflation. I will also show some numerical results and cosmological consequences of the model.
