Non-Abelian T-duality in pre-big-bang cosmology

摘要

We study the impact of non-Abelian T-duality transformations on a string based cosmological model. The implementation of the pre-big-bang scenario is investigated. We found a region of the dual phase where such a picture is possible. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 30]
