Consistent perturbations in an imperfect fluid

Show other versions (1)

We present a new prescription for analysing cosmological perturbations in a more-general class of scalar-field dark-energy models where the energy-momentum tensor has an imperfect-fluid form. This class includes Brans-Dicke models, f ( R ) gravity, theories with kinetic gravity braiding and generali...
