Asymptotic Regimes of Magnetic Bianchi Cosmologies

Autor: Horwood, J. T., Wainwright, J.

Publikováno v: Gen.Rel.Grav. 36 (2004) 799-823

We consider the asymptotic dynamics of the Einstein-Maxwell field equations for the class of non-tilted Bianchi cosmologies with a barotropic perfect fluid and a pure homogeneous source-free magnetic field, with emphasis on models of Bianchi type VII

Asymptotic dynamics of the exceptional Bianchi cosmologies

Autor: Hewitt, C. G., Horwood, J. T., Wainwright, J.

Publikováno v: Class.Quant.Grav. 20 (2003) 1743-1756

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 exceptional Bianchi cosmologies, which are of Bianchi type VI$_{-1/9}$. Thi

Late-time asymptotic dynamics of Bianchi VIII cosmologies

Autor: Horwood, J. T., Hancock, M. J., The, D., Wainwright, J.

Publikováno v: Class.Quant.Grav. 20 (2003) 1757-1778

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 perfect fluid with equation of state $p = (\gamma - 1)\mu
