A general theory of linear cosmological perturbations: stability conditions, the quasistatic limit and dynamics
We analyse cosmological perturbations around a homogeneous and isotropic background for scalar-tensor, vector-tensor and bimetric theories of gravity. Building on previous results, we propose a unified view of the effective parameters of all these theories. Based on this structure, we explore the vi...
