Dynamics of interacting monomial scalar field potentials and perfect fluids
Artur Alho, Vitor Bessa, Filipe C. Mena
Motivated by cosmological models of the early universe we analyse the dynamics of the Einstein equations with a minimally coupled scalar field with monomial potentials $V(ϕ)=\frac{…

Global dynamics of Yang-Mills field and perfect-fluid Robertson-Walker cosmologies
Artur Alho, Vitor Bessa, Filipe C. Mena
We apply a new global dynamical systems formulation to flat Robertson-Walker cosmologies with a massless and massive Yang-Mills field and a perfect-fluid with linear equation of st…

Inflation with a massive vector field nonminimally coupled to gravity
O. Bertolami, V. Bessa, J. Páramos
We study the possibility that inflation is driven by a massive vector field with SO(3) global symmetry nonminimally coupled to gravity. From an E^3-invariant Robertson-Walker metri…
