PEREIRA, S. H.; MENDONҫA, E. L.; PINHO S. S., A.  and  JESUS, J. F.. Cosmological bounds on open FLRW solutions of massive gravity. Rev. mex. astron. astrofis [online]. 2016, vol.52, n.1, pp.125-131. ISSN 0185-1101.

In this work we analysed some cosmological bounds concerning an open FLRW solution oí massive gravity. The constraints from recent observational H(z) data are found and the best fit values for the cosmological parameters are in agreement with the ɅCDM model, and also point to a nearly open spatial curvature, as expected from the model. The graviton mass dependence with the constant parameters α 3 and α4 related to the additional lagrangians terms of the model, are also analysed, and we obtain a strong dependence on such parameters, although the condition m g ≃ H 0 -1 seems dominant for a large range of the parameters α 3 and α4.
