Cosmological perturbations in generalised dark Lagrangians
James Edholm, Jonathan Pearson
We describe a new method to parameterise dark energy theories including massive gravity, elastic dark energy and tensor-metric theories. We first examine a framework to describe an…

The Equation of State Approach to Cosmological Perturbations in f(R) Gravity
Boris Bolliet, Richard A. Battye, Jonathan A. Pearson
The discovery of apparent cosmological acceleration has spawned a huge number of dark energy and modified gravity theories. The f(R) models of gravity are obtained when one replace…
