Stable super-inflating cosmological solutions in f(R)-gravity

Abstract

We consider super-inflating solutions in modified gravity for several popular families of f(R)f(R) functions. Using scalar field reformulation of f(R)f(R)-gravity we describe how the form of effective scalar field potential can be used for explaining existence of stable super-inflation solutions in the theory under consideration. Several new solutions of this type have been found analytically and checked numerically.
