Dark energy and dust matter phases from an exact $f(R)$-cosmology model

Astrophysics 2009-06-23 v1

Abstract

We show that dust matter-dark energy combined phases can be achieved by the exact solution derived from a power law f(R)f(R) cosmological model. This example answers the query by which a dust-dominated decelerated phase, before dark-energy accelerated phase, is needed in order to form large scale structures.
