String Cosmology and Chaos
arXiv:hep-th/0204017 · doi:10.1007/s00023-003-0923-0
Abstract
We briefly review three aspects of string cosmology: (1) the ``stochastic'' 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).
