The Dynamics of Multi-Scalar Field Cosmological Models and Assisted Inflation
A. A. Coley, R. J. van den Hoogen
We investigate the dynamical properties of a class of spatially homogeneous and isotropic cosmological models containing a barotropic perfect fluid and multiple scalar fields with…
Scalar Field Cosmologies with Barotropic Matter: Models of Bianchi class B
A. P. Billyard, A. A. Coley, R. J. van den Hoogen +2
We investigate in detail the qualitative behaviour of the class of Bianchi type B spatially homogeneous cosmological models in which the matter content is composed of two non-inter…
Scaling Solutions in Robertson-Walker Spacetimes
Robert J. van den Hoogen, Alan A. Coley, David Wands
We investigate the stability of cosmological scaling solutions describing a barotropic fluid with and a non-interacting scalar field with an exponential potential $V…
