Cosmology in massive gravity

We argue that more cosmological solutions in massive gravity can be obtained if the metric tensor and the tensor $Σ_{μν}$ defined by Stückelberg fields take the homogeneous and isotropic form. The standard cosmology with matter and radiation dominations in the past can be recovered and $Λ$CDM model is easily obtained. The dynamical evolution of the universe is modified at very early times.
