摘要：

Continuing on from previous works, we present a cosmological model in which dark matter and dark energy are modelled by scalar fields Phi and Psi, respectively, endowed with the scalar potentials V(Phi) = V-0[cosh(lambda root kappa(0)Phi) - 1] and (V) over tilde(Psi) = (V) over tilde(0)[sinh(alpha root kappa(0)Psi)](beta). This model contains a 95% scaIar field. We obtain that the scalar dark matter mass is m(Phi) similar to 10(-26) eV. The solution obtained allows us to recover the success of standard cold dark matter. The implications on the formation of structure are reviewed. We obtain that the minimal cut-off radio for this model is r(c) similar to 1.2 kpc.
