Cosmological dynamical systems
Genly Leon, Carlos R. Fadragas
In this book are studied, from the perspective of the dynamical systems, several Universe models. In chapter 1 we give a bird's eye view on cosmology and cosmological problems. Cha…
Some remarks about non-minimally coupled scalar field models
Carlos R. Fadragas, Genly Leon
Several results related to flat Friedmann-Lema\^ıtre-Robertson-Walker models in the conformal (Einstein) frame of scalar-tensor gravity theories are extended. Scalar fields with ar…
Dynamical analysis of anisotropic scalar-field cosmologies for a wide range of potentials
Carlos R. Fadragas, Genly Leon, Emmanuel N. Saridakis
We perform a detailed dynamical analysis of anisotropic scalar-field cosmologies, and in particular of the most significant Kantowski-Sachs, Locally Rotationally Symmetric (LRS) Bi…
Thawing models in the presence of a generalized Chaplygin gas
Sergio del Campo, Carlos R. Fadragas, Ramon Herrera +3
In this paper we consider a cosmological model whose main components are a scalar field and a generalized Chaplygin gas. We obtain an exact solution for a flat arbitrary potential.…
Asymptotic behavior of a scalar field with an arbitrary potential trapped on a Randall-Sundrum's braneworld: the effect of a negative dark radiation term on a Bianchi I brane
Dagoberto Escobar, Carlos R. Fadragas, Genly Leon +1
In this work we present a phase space analysis of a quintessence field and a perfect fluid trapped in a Randall-Sundrum's Braneworld of type 2. We consider a homogeneous but anisot…
Phase space analysis of quintessence fields trapped in a Randall-Sundrum Braneworld: anisotropic Bianchi I brane with a Positive Dark Radiation term
Dagoberto Escobar, Carlos R. Fadragas, Genly Leon +1
In this paper we investigate, from the dynamical systems perspective, the evolution of an scalar field with arbitrary potential trapped in a Randall-Sundrum's Braneworld of type 2.…
