The Similarity Hypothesis in General Relativity
B. J. Carr, A. A. Coley
Self-similar models are important in general relativity and other fundamental theories. In this paper we shall discuss the ``similarity hypothesis'', which asserts that under a var…
Asymptotic analysis of spatially inhomogeneous stiff and ultra-stiff cosmologies
A. A. Coley, W. C. Lim
We calculate analytically the past asymptotic decay rates close to an initial singularity in general G_0 spatially inhomogeneous perfect fluid models with an effective equation of…
A note on the peeling theorem in higher dimensions
A. Pravdova, V. Pravda, A. Coley
We demonstrate the ``peeling property'' of the Weyl tensor in higher dimensions in the case of even dimensions (and with some additional assumptions), thereby providing a first ste…
Inhomogeneous perturbations of plane-wave spacetimes
Sigbjorn Hervik, Alan Coley
Recently it was shown that the exact cosmological solutions known as the vacuum plane-wave solutions are late-time attractors for an open set of the spatially homogeneous Bianchi u…
The Dynamics of Brane-World Cosmological Models
A. A. Coley
Brane-world cosmology is motivated by recent developments in string/M-theory and offers a new perspective on the hierarchy problem. In the brane-world scenario, our Universe is a f…
Cosmological Solutions in Macroscopic Gravity
A. A. Coley, N. Pelavas, R. M. Zalaletdinov
In the macroscopic gravity approach to the averaging problem in cosmology, the Einstein field equations on cosmological scales are modified by appropriate gravitational correlation…
