The present study reports a reconstruction scheme for f(R) gravity with the scale factor a(t) ∝ (t∗ − t) 2 c 2 describing the pre-bounce ekpyrotic contraction, where t∗ is the big crunch time. The reconstructed f(R) is used to derive expressions for density and pressure contributions, and the equation of state parameter resulting from this reconstruction is found to behave ...
