From inflation to Friedmann regime in R2 cosmology
A cosmological model describing the different stages of the universe, i.e.: inflation, radiation dominated period and matter dominated (Friedmann-like) period is shown. The model consists of the usual gravitational lagrangian with a σ R2 term, and, for the matter content, the lagrangian of a massive...
