Stability properties and asymptotics for N non-minimally coupled scalar fields cosmology
L. Brenig, A. Figueiredo, E. Gunzig +2
We consider here the dynamics of some homogeneous and isotropic cosmological models with interacting classical scalar fields non-minimally coupled to the spacetime curvature, a…

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…

Superinflation, quintessence, and the avoidance of the initial singularity
A. Saa, E. Gunzig, L. Brenig +3
We consider the dynamics of a spatially flat universe dominated by a self-interacting nonminimally coupled scalar field. The structure of the phase space and complete phase portrai…
