# Hyperbolic space cosmologies

@article{Chen2003HyperbolicSC, title={Hyperbolic space cosmologies}, author={Chiang-Mei Chen and P. M. Ho and Ishwaree P. Neupane and Nobuyoshi Ohta and John E. Wang}, journal={Journal of High Energy Physics}, year={2003}, volume={2003}, pages={058-058} }

We present a systematic study of accelerating cosmologies obtained from M/string theory compactifications of hyperbolic spaces with time-varying volume. A set of vacuum solutions where the internal space is a product of hyperbolic manifolds is found to give qualitatively the same accelerating four-dimensional FLRW universe behavior as a single hyperbolic space. We also examine the possibility that our universe is a hyperbolic space and provide exact Milne type solutions, as well as intersecting…

We begin by reviewing the results on the decay of unstable D-branes in type II string theory, and the open–closed string duality proposal that arises from these studies. We then apply this proposal…

Phase space analysis of quintessence cosmologies with a double exponential potential

We use phase space methods to investigate closed, flat, and open Friedmann–Robertson–Walker cosmologies with a scalar potential given by the sum of two exponential terms. The form of the potential is…

Space-like branes, accelerating cosmologies and the near `horizon' limit

It is known that there exist two different classes of time dependent solutions in the form of space-like (or S)-branes in the low energy M/string theory. Accelerating cosmologies are known to arise…

We consider the cosmological models for the higher dimensional space-time which includes the curvatures of our space as well as the curvatures of the internal space. We find that the condition for…

It is shown that the spectrum of Kaluza-Klein modes is radically altered, which allows the early Universe to evolve normally up to substantial temperatures, and completely negates the astrophysical constraints on M(*.
