Exact $f(R)$-cosmological model coming from the request of the existence of a Noether symmetry

Abstract

We present an $f(R)$-cosmological model with an exact analytic solution, coming from the request of the existence of a Noether symmetry, which is able to describe a dust-dominated decelerated phase before the current accelerated phase of the universe.
