Dynamical analysis of generalized Galileon cosmology
We perform a detailed dynamical analysis of generalized Galileon cosmology, incorporating also the requirements of ghost and instabilities absence. We find that there are not any new stable late-timeExpand
Dynamical Systems and Cosmology
Dynamical systems theory is especially well-suited for determining the possible asymptotic states (at both early and late times) of cosmological models, particularly when the governing equations areExpand
Inhomogeneous cosmologies with cosmological constant
Abstract We give a new class of exact inhomogeneous solutions to Einstein's equations with non-zero cosmological constant and zero pressure. They generalize the de Sitter space-time and evolveExpand
Dynamical Analysis of Anisotropic Inflation
The inflaton coupling to a vector field via the f (φ) FμνF term is used in several contexts in the literature, such as to generate primordial magnetic fields, to produce statistically anisotropicExpand

We present the dynamical analysis for interacting quintessence, considering linear cosmological perturbations. Matter perturbations improve the background analysis and viable critical pointsExpand
Growth of structure in the Szekeres class-II inhomogeneous cosmological models and the matter-dominated era
This study belongs to a series devoted to using the Szekeres inhomogeneous models in order to develop a theoretical framework where cosmological observations can be investigated with a wider range ofExpand
A class of inhomogeneous cosmological models
All solutions of Einstein's field equations representing irrotational dust and possessing a metric of the formds2=dt2−e2αdr2−e2β(dy2+dz2) are found. The new metrics generalize the earlierExpand
A class of Szekeres space-times with cosmological constant
We present a generalization of a class of Szekeres space-times. The new solutions satisfy Einstein's equations with a cosmological constant and have the same geometrical properties as theExpand

A complete global analysis of spatially flat, four-dimensional cosmologies derived from the type IIA string and M-theory effective actions is presented. A non-trivial Ramond-Ramond sector isExpand

We investigate the local non--linear dynamics of irrotational dust with vanishing magnetic part of the Weyl tensor, $H_{ab}$. Once coded in the initial conditions, this dynamical restriction isExpand
