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…
Dynamical study of the singularities of gravity in the presence of non-minimally coupled scalar fields
L. R. Abramo, L. Brenig, E. Gunzig +1
We investigate the dynamics of Einstein equations in the vicinity of the two recently described types of singularity of anisotropic and homogeneous cosmological models described by…
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…
