Non-Abelian T-duality in Pre-Big-Bang Cosmology

TL;DR

This paper explores how non-Abelian T-duality transformations affect a string cosmological model, demonstrating a dual phase where the pre-big-bang scenario remains viable.

Contribution

It introduces the application of non-Abelian T-duality to pre-big-bang cosmology, identifying conditions for a consistent dual phase.

Findings

Existence of a dual phase compatible with pre-big-bang scenario

Non-Abelian T-duality can be implemented in string cosmology models

Potential for new insights into early universe dynamics

Abstract

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.
