A maximum magnetic moment to angular momentum conjecture
John D. Barrow, G. W. Gibbons
Conjectures play a central role in theoretical physics, especially those that assert an upper bound to some dimensionless ratio of physical quantities. In this paper we introduce a…
The Weyl tensor in Spatially Homogeneous Cosmological Models
John D. Barrow, Sigbjorn Hervik
We study the evolution of the Weyl curvature invariant in all spatially homogeneous universe models containing a non-tilted gamma-law perfect fluid. We investigate all the Bianchi…
Inflationary Models with Logarithmic Potentials
John D. Barrow, Paul Parsons
We examine inflationary universe models driven by scalar fields with logarithmic potentials of the form . Combining the slow-roll approximation with asympt…
Generalised Scalar Field Potentials and Inflation
Paul Parsons, John D. Barrow
We investigate the range of inflationary universe models driven by scalar fields possessing a general interaction potential of the form . Power-law, de…
