Practical solutions for perturbed f(R) gravity
We examine the accuracy of the quasistatic approximation and a parametric form commonly employed for evolving linear perturbations in f(R) gravity theories and placing cosmological constraints. In particular, we analyze the nature and the importance of the near-horizon effects that are often neglect...
