Superinflation and quintessence in the presence of an extra field
A. Figueiredo, T. M. Rocha Filho, E. Gunzig +2
We discuss the implication of the introduction of an extra field to the dynamics of a scalar field conformally coupled to gravitation in a homogeneous isotropic spatially flat univ…

On the singularities of gravity in the presence of non-minimally coupled scalar fields
L. Raul Abramo, Leon Brenig, Edgard Gunzig +1
We investigate the robustness of some recent results obtained for homogeneous and isotropic cosmological models with conformally coupled scalar fields. For this purpose, we investi…
