Dynamical Equilibrium States of a Class of Irrotational Non-Orthogonally Transitive Cosmologies I: The Conjecture of Chaotic Cosmological Inhomogeneity
C. G. Hewitt
The Einstein field equations for a class of irrotational non-orthogonally transitive cosmologies are written down as a system of partial differential equations. The equilib…
Dynamical Equilibrium States of a Class of Irrotational Non-Orthogonally Transitive Cosmologies II: Models With One Hypersurface-Orthogonal Killing Vector Field
Sepehr Rashidi, C. G. Hewitt, Benoit Charbonneau
We consider a class of inhomogeneous self-similar cosmological models in which the perfect fluid flow is tangential to the orbits of a three-parameter similarity group. We restrict…
Asymptotic dynamics of the exceptional Bianchi cosmologies
C. G. Hewitt, J. T. Horwood, J. Wainwright
In this paper we give, for the first time, a qualitative description of the asymptotic dynamics of a class of non-tilted spatially homogeneous (SH) cosmologies, the so-called excep…
The asymptotic regimes of tilted Bianchi II cosmologies
C. G. Hewitt, R. Bridson, J. Wainwright
In this paper we give, for the first time, a complete description of the dynamics of tilted spatially homogeneous cosmologies of Bianchi type II. The source is assumed to be a perf…
