The Asymptotic Behaviour of Tilted Bianchi type VI0 Universes
نویسنده
چکیده
We study the asymptotic behaviour of the Bianchi type VI0 universes with a tilted γ-law perfect fluid. The late-time attractors are found for the full 7-dimensional state space and for several interesting invariant subspaces. In particular, it is found that for the particular value of the equation of state parameter, γ = 6/5, there exists a bifurcation line which signals a transition of stability between a non-tilted equilibrium point to an extremely tilted equilibrium point. The initial singular regime is also discussed and we argue that the initial behaviour is chaotic for γ < 2.

The Future of Tilted Bianchi Universes
An asymptotic stability analysis of spatially homogeneous models of Bianchi type containing tilted perfect fluids is performed. Using the known attractors for the non-tilted Bianchi type universes, we check whether they are stable against perturbations with respect to tilted perfect fluids. We perform the analysis for all Bianchi class B models and the Bianchi type V I0 model. In particular, we...

We show that the tilted perfect fluid Bianchi VI0 family of self-similar models found by Rosquist and Jantzen [K. Rosquist and R. T. Jantzen, Exact power law solutions of the Einstein equations, 1985 Phys. Lett. 107A 29-32] is the most general class of tilted self-similar models but the state parameter γ lies in the interval (
متن کاملBianchi Cosmologies: a Tale of Two Tilted Fluids
We use a dynamical systems approach to study Bianchi type VI0 cosmological models containing two tilted γ-law perfect fluids. The full state space is 11-dimensional, but the existence of a monotonic function simplifies the analysis considerably. We restrict attention to a particular, physically interesting, invariant subspace and find all equilibrium points that are future stable in the full 11...
متن کاملThe Late-time Behaviour of Vortic Bianchi Type Viii Universes
We use the dynamical systems approach to investigate the Bianchi type VIII models with a tilted γ-law perfect fluid. We introduce expansion-normalised variables and investigate the late-time asymptotic behaviour of the models and determine the latetime asymptotic states. For the Bianchi type VIII models the state space is unbounded and consequently, for all non-inflationary perfect fluids, one ...

Exact models for Bianchi VI0 spacetimes with multiple scalar fields with exponential potentials have been derived and analysed. It has been shown that these solutions, when they exist, attract neighbouring solutions in the two cases corresponding to interacting and non-interacting fields. Unlike the results obtained in a previous work dealing with the late-time inflationary behaviour of Bianchi...
