In this paper we investigate asymptotic isotropization. We derive the asymptotic dynamics of spatially inhomogeneous cosmological models with a perfect fluid matter source and a positive cosmological constant near the de Sitter equilibrium state at late times, and near the flat FL equilibrium state at early times. Our results show that there exists an open set of solutions approaching the de Sitter state at late times, consistent with the cosmic no-hair conjecture. On the other hand, solutions… 
The Dynamics of Inhomogeneous Cosmologies
In this thesis we investigate cosmological models more general than the isotropic and homogeneous Friedmann-Lemaitre models. We focus on cosmologies with one spatial degree of freedom, whose matter
Future dynamics of FLRW for the massless-scalar field system with positive cosmological constant
We consider solutions to the Einstein-massless-scalar field system with a positive cosmological constant, arising from sufficiently regular, near-FLRW (Friedmann-Lemaître-Robertson-Walker), initial
Asymptotics of Solutions of the Einstein Equations with Positive Cosmological Constant
Abstract.A positive cosmological constant simplifies the asymptotics of forever expanding cosmological solutions of the Einstein equations. In this paper a general mathematical analysis on the level
Asymptotic analysis of spatially inhomogeneous stiff and ultra-stiff cosmologies
We calculate analytically the past asymptotic decay rates close to an initial singularity in general G0 spatially inhomogeneous perfect fluid models with an effective equation of state which is stiff
The dynamics of Lemaître–Tolman cosmologies
In this paper we give a coordinate-independent analysis of the dynamics of the spherically symmetric Lemaître–Tolman (LT) cosmologies, emphasizing their relation with the Friedmann–Lemaître (FL)
Tilted Bianchi VII0 cosmologies—the radiation bifurcation
We derive the late-time behaviour of tilted Bianchi VII0 cosmologies with an irrotational radiation fluid as source, and give the asymptotic form of the general solution as t → +∞, making comparisons
Fluid observers and tilting cosmology
We study perfect fluid cosmological models with a constant equation of state parameter γ in which there are two naturally defined timelike congruences, a geometrically defined geodesic congruence and
Evolution of a simple inhomogeneous anisotropic cosmological model with diffusion
We investigate a simple inhomogeneous anisotropic cosmology (plane symmetric G2 model) filled with a tilted perfect fluid undergoing velocity diffusion on a scalar field. Considered are two types of
Spherically symmetric Einstein-aether perfect fluid models
We investigate spherically symmetric cosmological models in Einstein-aether theory with a tilted (non-comoving) perfect fluid source. We use a 1+3 frame formalism and adopt the comoving aether gauge
Dynamics of the anisotropic Kantowsky–Sachs geometries in Rn gravity
We construct general anisotropic cosmological scenarios governed by an f(R) gravitational sector. Focusing then on Kantowski–Sachs geometries in the case of Rn-gravity, and modeling the matter


Cosmic no-hair: nonlinear asymptotic stability of de Sitter universe
We study the asymptotic stability of de Sitter spacetime with respect to nonlinear perturbations, by considering second-order perturbations of a flat Friedmann–Lemaitre–Robertson–Walker universe with
Late-time asymptotic dynamics of Bianchi VIII cosmologies
In this paper we give, for the first time, a complete description of the late-time evolution of non-tilted spatially homogeneous cosmologies of Bianchi type VIII. The source is assumed to be a
Isotropization of two-component fluids
We consider the problem of late-time isotropization in spatially homogeneous but anisotropic cosmological models when the source of the gravitational field consists of two noninteracting perfect
Velocity‐Dominated Singularities in Irrotational Dust Cosmologies
We consider irrotational dust solutions of the Einstein equations. We define ``velocity‐dominated'' singularities of these solutions. We show that a velocity‐dominated singularity can be considered
A Dynamical Systems Approach to Geodesics in Bianchi Cosmologies
To understand the observational properties of cosmological models, in particular, the temperature of the cosmic microwave background radiation, it is necessary to study their null geodesics.
The Past attractor in inhomogeneous cosmology
We present a general framework for analyzing spatially inhomogeneous cosmological dynamics. It employs Hubble-normalized scale-invariant variables which are defined within the orthonormal frame
Global existence and asymptotic behaviour in the future for the Einstein-Vlasov system with positive cosmological constant
The behaviour of expanding cosmological models with collisionless matter and a positive cosmological constant is analysed. It is shown that under the assumption of plane or hyperbolic symmetry the
Isotropic singularities in cosmological models
Motivated by the ideas of quiescent cosmology and Penrose's Weyl tensor hypothesis concerning the 'big bang', the authors give a geometric (and hence coordinate-independent) definition of the concept
Isotropic Cosmological Singularities: I. Polytropic Perfect Fluid Spacetimes
Abstract We consider the conformal Einstein equations for 1⩽ γ ⩽2 polytropic perfect fluid cosmologies which admit an isotropic singularity. For 1 γ ⩽2 it is shown that the Cauchy problem for these
Asymptotic behavior of homogeneous cosmological models in the presence of a positive cosmological constant
We examine the late-time behavior of intially expanding homogeneous cosmological models satisfying Einstein's equation with a positive cosmological constant $\ensuremath{\Lambda}$. It is shown that
