String Cosmology and Chaos
نویسنده
چکیده
We briefly review three aspects of string cosmology: (1) the " stochas-tic " approach to the pre-big bang scenario, (2) the presence of chaos in the generic cosmological solutions of the tree-level low-energy effective actions coming out of string theory, and (3) the remarkable link between the latter chaos and the Weyl groups of some hyperbolic Kac-Moody algebras. Talk given at the Francqui Colloquium " Strings and Gravity: Tying the Forces Together " (Brussels, October 2001).

String Cosmology and Chaos
We investigate Bianchi type IX ”Mixmaster” universes within the framework of the low-energy tree-level effective action for string theory, which (when the ”stringy” 2-form axion potential vanishes) is formally the same as the Brans-Dicke action with ω = −1. We show that, unlike the case of general relativity in vacuum, there is no Mixmaster chaos in these string cosmologies. In the Einstein fra...
متن کاملIs There Chaos in Low-Energy String Cosmology?
Bianchi type IX, ’Mixmaster’ universes are investigated in low-energyeffective-action string cosmology. We show that, unlike in general relativity, there is no chaos in these string cosmologies for the case of the tree-level action. The characteristic Mixmaster evolution through a series of Kasner epochs is studied in detail. In the Einstein frame an infinite sequence of chaotic oscillations of...
متن کاملOscillatory Behaviour in Homogeneous String Cosmology Models
Some spatially homogeneous Bianchi type I cosmological models filled with homogeneous “electric” p-form fields are shown to mimic the never-ending oscillatory behaviour of generic string cosmologies established recently. The validity of the “Kasner-free-flights plus collisions-on-potential-walls” picture is also illustrated in the case of known, non-chaotic, superstring solutions.
متن کاملChaos in superstring cosmology
It is shown that the general solution near a spacelike singularity of the Einstein-dilaton- p-form field equations relevant to superstring theories and M theory exhibits an oscillatory behavior of the Belinskii-Khalatnikov-Lifshitz type. String dualities play a significant role in the analysis.
متن کاملString Gas Cosmology L a T E X 2 Ε Version
String gas cosmology is a string theory-based approach to early universe cosmology which is based on making use of robust features of string theory such as the existence of new states and new symmetries. A first goal of string gas cosmology is to understand how string theory can effect the earliest moments of cosmology before the effective field theory approach which underlies standard and infl...
