Abstract
In this paper we study the cosmological evolution of the universe filled with a perfect fluid in the Eddington-inspired Born-Infeld gravity. Applying an alternative method in which the evolution of the scale factor for this theory is linked to the cosmographic parameters, we obtain a dynamical dark energy solution where the singularity (through a regular bounce or a loitering phase) still can be avoided for with . For the range , the results lead us to universes that experience an unlimited rate of expansion with finite density. Also, we obtain a possible maximum value of at the cosmic bounce point.
