A Closed Bianchi I Universe in String Theory

High Energy Physics - Theory 2009-10-22 v4

Abstract

A special Bianchi I universe is constructed in  4D ~4D~ string theory. Geometrically it represents a  3D ~3D~ anti-de-Sitter space crossed with a flat direction whereas in terms of an associated conformal field theory it is an extremal case of a gauged WZWN theory with target the coset  SU(1,1)×R2/R ~SU(1,1) \times R^2 / R~. Some of its properties are discussed.
