About this document
Friedmann Equations for f (R) = ΑR + β by AnujThakur is a document available to read on EtoBox.
The document derives the Friedmann equations for a modified gravity model f(R) = αR + β in natural units, presenting equations in both cosmic and conformal time. It includes specific equations for Hubble parameters and their derivatives, incorporating total density and pressure. Additionally, the CLASS code implementation of these equations is outlined for computing expansion rates in cosmological models.
