Abstract:
An symmetry of the manifold of string vacua that do not depend on (out of ) space-time coordinates has been recently identified. Here we write down, for , the low energy equations of motion and their general solution in a manifestly -invariant form, pointing out an amusing similarity with the renormalization group framework. Previously considered cosmological and black hole solutions are recovered as particular examples.Note:
