On the classification of spatially homogeneous 4D string backgrounds

A classification of all possible spatially homogeneous 4D string backgrounds (HSBs) has been obtained by appropriate ramification of the existing nine Bianchi types of homogeneous 3D spaces. A total of 24^2=576 HSBs which have been classified as distinct contains a subclass of 192 which includes all...

description A classification of all possible spatially homogeneous 4D string backgrounds (HSBs) has been obtained by appropriate ramification of the existing nine Bianchi types of homogeneous 3D spaces. A total of 24^2=576 HSBs which have been classified as distinct contains a subclass of 192 which includes all possible FRW models as well as those in which SO(3) isotropy is attained asymptotically. A discussion of these results also aims to fascilitate the identification of HSBs which have already appeared in the literature. The basic physical perspective of the parameters of classification is outlined together with certain features relating to deeper aspects of string theory.
