Abstract

In this work we have analysed some cosmological bounds concerning an open FLRW solution of massive gravity. The constraints with recent observational H(z)H(z) data were found and the best fit values for the cosmological parameters are in agreement with the Λ\LambdaCDM model, and also point to a nearly open spatial curvature, as expected from the model. The graviton mass dependence with the constant parameters α3\alpha_3 and α4\alpha_4, related to the additional lagrangians terms of the model, are also analysed, and we have obtained a strong dependence with such parameters, although the condition mgH01m_g\simeq H_0^{-1} seems dominant for a long range of the parameters α3\alpha_3 and α4\alpha_4.
