Qualitative analysis of Kantowski-Sachs metric in a generic class of models
Genly Leon, Armando A. Roque
In this paper we investigate, from the dynamical systems perspective, the evolution of a Kantowski-Sachs metric in a generic class of models. We present conditions (i. e., d…
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.…
Cosmological behavior in extended nonlinear massive gravity
Genly Leon, Joel Saavedra, Emmanuel N. Saridakis
We perform a detailed dynamical analysis of various cosmological scenarios in extended (varying-mass) nonlinear massive gravity. Due to the enhanced freedom in choosing the involve…
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…
