Abstract:
We argue that more cosmological solutions in massive gravity can be obtained if the metric tensor and the tensor Σμν 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 ΛCDM model is easily obtained. The dynamical evolution of the universe is modified at very early times.
