  1. We introduce a cosmological model in the framework of Generalised Massive Gravity. This theory is an extension of non-linear massive gravity with a broken translation symmetry in the Stückelberg space. In a recent work, we showed the existence of cosmological solutions stable against linear perturbations. In the present paper, we build up on the previous result and study the evolution of the ...

    and mass-varying massive gravity [14] where the mass parameters are upgraded to functions of the new scalar. Almost all extensions, with varying success in sustaining a stable cosmology, introduce new degrees of freedom in addition to the 5 of dRGT massive gravity. Generalized massive gravity (GMG) is an extension

Thus the growth rate reflects a competition between the gravitational force and the cosmic expansion, with growth slowed down but still proceeding forever. A

    The nature of the fuel that drives today's cosmic acceleration is an open and tantalizing mystery. The braneworld theory of Dvali, Gabadadze, and Porrati (DGP) provides a context where late-time acceleration is driven not by some energy-momentum component (dark energy), but rather is the manifestation of the excruciatingly slow leakage of gravity off our four-dimensional world into an ...
