Quasi-isotropic cycles and non-singular bounces in a Mixmaster cosmology
Chandrima Ganguly, Marco Bruni
A Bianchi IX Mixmaster spacetime is the most general spatially homogeneous solution of Einstein's equations and it can represent the space-averaged Universe. We introduce two novel…
Inhomogeneous Initial Data and Small-Field Inflation
M. C. David Marsh, John D. Barrow, Chandrima Ganguly
We consider the robustness of small-field inflation in the presence of scalar field inhomogeneities. Previous numerical work has shown that if the scalar potential is flat only ove…
Evolution of Cyclic Mixmaster Universes with Non-comoving Radiation
Chandrima Ganguly, John D. Barrow
We study a model of a cyclic, spatially homogeneous, anisotropic 'mixmaster' universe of Bianchi type IX, containing a radiation field with non-comoving ('tilted' with respect to t…
The Shape of Bouncing Universes
John D. Barrow, Chandrima Ganguly
What happens to the most general closed oscillating universes in general relativity? We sketch the development of interest in cyclic universes from the early work of Friedmann and…
Cyclic Mixmaster Universes
John D. Barrow, Chandrima Ganguly
We investigate the behaviour of bouncing Bianchi type IX `Mixmaster' universes in general relativity. This generalises all previous studies of the cyclic behaviour of closed spatia…
