Abstract: (Elsevier)
The concept of discrete scale-factor-duality transformations is extended to a full, continuous O( d , d ) group. The action of the group transforms “cosmological” solutions of the low-energy, string-modified Einstein equations (including non-trivial dilaton and antisymmetric tensor fields) into other solutions, thus representing the natural generalization of Narain's construction to time-dependent, not-necessarily-compact manifolds. Possible connections with 2D black holes are also pointed out.- string model
