Cosmological perturbations in generalised dark Lagrangians
Abstract We describe a new method to parameterise dark energy theories including massive gravity, elastic dark energy and tensor-metric theories. We first examine the existing framework which describes any second order Lagrangian which depends on the variation of the metric and find new constraints...
