Oscillating cosmological correlations in f(R) gravity

The purpose of this paper is to investigate the oscillatory behavior of the universe through a Schr"odinger-like Friedmann equation and a modified gravitational background described by the theory of f ® gravity. The motivation for this stems from the observed periodic behaviour of large-scale cosmological structures when described within the scope of the general theory of relativity. The analysis of the modified Friedmann equation for the dust epoch in power-law f ® models results in different behaviors for the wave-function of the universe.
