  1. We present a thorough analysis of the cosmological perturbations in Generalised Massive Gravity. This is an extension of de Rham-Gabadadze-Tolley theory where the translation invariance in the Stückelberg field space is broken. This allows the mass parameters to be promoted to functions of the Stückelberg fields. We consider an exact cosmological background in this theory and study the ...

    [20]. For anti-de Sitter, the cosmology cannot sustain an accelerated expansion [21]. The lack of stable cosmologies in dRGT massive gravity motivates extensions of the theory. One example is the bimetric theory [22], where the fiducial metric is promoted toa dynamical variable.Bimetric cosmology suffersfroma

    The cosmology is an extension of the self-accelerating branch of the constant mass parameter theory, but now all five massive graviton polarisations propagate. For concreteness, we consider a minimal version of the theory where cosmology undergoes an accelerated expansion at late times and show that the perturbative stability is preserved for a ...

    We introduce a cosmological model in the framework of generalized massive gravity. This theory is an extension of nonlinear massive gravity with a broken translation symmetry in the St\"uckelberg 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 ...
